lAufodafa Carburettor Manual Introduction This manual is a comprehensive source of information for all technicians and carburettor specialists and covers the majority of European and Japanese carburettor models, produced during the last decade. The manual is divided into three sections.

The first section comprises the specific chapters for each group of models using a particular carburettor. There are over 200 of these selfcontained chapters, containing all the specific details of preparatory conditions, adjustments of idle speed, fast idle speed, CO level, choke pulldown, float level, accelerator pump, throttle valve gap and any other relevant checks and calibrations. All the procedures are accompanied by a series of clear line drawings, highlighting the position of adjusting screws and measurement pOints. In the case of electronically controlled carburettors, wiring diagrams are also included.

The second section comprises Vacuum Connection diagrams giVing detailed illustrations of the complex vacuum connections between the carburettor and the various sensors and actuators.

The third section lists Technical Data for all the carburettors and models covered by this manual. For ease of use, each model has its own column of data and specifications.

GENERAL WORKSHOP PROCEDURES General layout

The checking and adjustment procedures for each car and carburettor type are arranged on a double page layout for clarity and ease of use. The procedures are divided into two sections, ADJUSTMENTS, Carburettor Installed and, if necessary, ADJUSTMENTS, Carburettor Removed.

Tamperproofing

Details of the type of seals fitted, when appropriate, are provided at the start of most ADJUSTMENTS, Carburettor Installed section, together with the method of removal and replacement. Generally the adjustment screws are either in a recessed housing, protected by a plug which can be levered out, or in the case of a protruding screw, a plastic cap, which can be levered or broken off to give access. In all cases the tamperproofing seal is not re-useable.

Idle Adjustment

The Idle Adjustment section of each chapter is divided into three sections to cover 'Idle Speed & CO Level', 'Idle Basic Setting' and 'Fast Idle Speed'. Preparatory Conditions The adjustment of idle speed and CO level must be carried out precisely to ensure that the car's exhaust emissions are at the specified level and that the engine is giving the best fuel economy and performance. Adjustments should be made only after the following conditions have been met: •

Engine must be run-in (adjustments made to an engine not run-in may alter rapidly).

• • • • • • •

Valve clearances correctly set. Dwell angle within specification. Ignition timing correctly set for petrol grade in use. Correct grade of spark plugs in use and correctly gapped. HT plug leads, cap and rotor arm in serviceable condition. Carburettor linkage(s) correctly adjusted and lubricated. Air cleaner in position and element clean (certain models may require the removal of the air cleaner, details are given in the appropriate section). • Induction system without air leaks (vacuum hoses, breather •

hoses etc.). Exhaust system in serviceable leak-free condition.

• Choke valve fully open. • Engine at normal running temperature. Engine should be run at fast idle until thermostat opens or specified temperature is reached. Do not warm up engine at idle speed as false CO levels may be obtained . • All electrical loads should normally be switched off, however certain models should have the cooling fan running and/or the head lamps switched on. Details are given in the appropriate section . • Test instruments such as the rev-counter and CO meter should be connected in accordance with the instrument manufacturer's instructions.

Idle Basic Setting The Idle Basic Setting should normally require adjustment only it- the Idle Speed and CO Level adjustments fail to produce a satisfactory condition within the specified limits or if the throttle valve basic setting has been inadvertently disturbed.

Other Adjustments Checking and adjustment procedures for fast idle speed, automatic choke, choke valve gap etc. are detailed in the text under the appropriate headings. These adjustments are not normally required and should only be undertaken when specific problems are experienced. Generally the 'Preparatory Conditions' for Idle Adjustment apply, but specific conditions are given at the start of each section where appropriate.

Special Notes Details requiring particular attention, or further operations which should be referred to, are given under the above heading.

Vacuum Connections These diagrams show the vacuum pipe connections between the carburettor, air cleaner, distributor and other sensors.

Specifications Details of the idle speed and CO level are provided at the beginning of the appropriate section whenever possible. Full identification details for each car and carburettor are provided in Technical Data, and for ease of use each model range has its own column of data and specifications. Adjustment data for valve clearances, ignition timing etc., may be obtained from the Autodata Technical Data Manual.

additional enrichment provided by a delay valve provided during cranking and as the engine starts to run. As the coolant temperature rises a capsule progressively reduces the air/fuel mixture until at a predetermined temperature the outlet port closes. Any increase in manifold depression during warm-up causes the fuel needle to rise increasing fuel flow whilst accelerating. For hard acceleration an accelerator pump at the base of the unit injects a metered amount of fuel. Special Note: The A.S.U. is flow tested and adjusted at the factory and cannot be set in service. It should not be dismantled other than for renewal of diaphragms. 3.1 Checking Operation a} Remove air cleaner and intake tube assembly. b} Ensure that intake pipe and outlet hose are secure and fuel level in LH carburettor is correct. c} With cold engine: Start engine (for five seconds) and stop. d} Remove outlet hose, outlet port should be moist with fuel. e} If excessively wet with fuel check to see if diaphragm outlet port is dry. f} Refit outlet hose, partially block inlet port and cran k engine for five seconds.

ADJUSTMENTS, Carburettor installed 1. GENERAL The 2BE-carburettor is completely controlled by an ECU (Electronic Control Unit). which is situated inside the glove box. Before checking mechanical parts, look for faults in the electrical system: check plug connections for humidity, corrosion and security. The ECU should be checked with an engine test unit according to manufacturer's specifications. An easier method is to substitute the ECU with a unit which is known to be good. If a fault is still apparent, check the wiring loom carefully (see section 5). Idle speed cannot be adjusted as it is controlled by the ECU. Check all moving components for free movement. Fuel level cannot be adjusted and depends on accurate float weight.

a) Remove air cleaner assembly. b) Start engine and allow to idle. Engine must be at normal operating temperature. c) At rear of choke housing, push driving lever (A) up to noticeable stop, using a screwdriver (Fig. 5). Special Note: Do not push driving lever too strongly against stop, as this may cause diaphragm in pull-down unit to be pulled back and result in measuring errors.

d) Check gap between lower edge of choke plate and air intake wall, with suitable size of gauge or drill (B). Ensure drill/gauge is a tight fit to eliminate play in choke linkage. e) If clearance is outside specified limits, adjust by turning adjusting screw at pull-down diaphragm housing (Fig. 6). Screwing in reduces gap, and vice-versa.

a) With engine running at idle, disconnect vacuum hose from throttle valve vacuum governor, then stop engine. b) Check that throttle lever (A) rests against throttle stop screw (B, Fig. 1). c) Check that pump lever just contacts pump plunger without play, but does not push plunger in. d) If necessary, adjust by turning nut (A) on pump link rod in appropriate direction (Fig. 7). e) Check clearance (x) between end of stroke limiter screw and pump cover. This should be 4,0 mm for M123 engine; 4,5 mm for Ml10 engine. f) If necessary, adjust by turning screw (B) in appropriate direction.

Special Note: To avoid measuring errors, make sure that float pivot pin is always resting on bottom of its housing during check.

c) Using a depth measuring gauge, measure distance (x) (Fig. 8) from face of carburettor housing without gasket to su rface of fuel at edge of float chamber at a point 18 mm from float centre-line (Fig. 9). d) If dimension is outside specified limits, remove float and bend arm in appropriate direction at point (A) immediately in front of pivot pin hole to achieve correct setting. e) Refit carburettor top cover, using a new gasket.

Tamperproof caps are fitted to the adjustment screws to prevent indiscriminate tampering with settings. If adjustments are necessary, the caps can be removed, using pliers and taking care not to damage the screws. Replacement caps should be fitted, when final tuning has been completed, in accordance with the following procedure. Extreme care must be taken to ensure that the final settings are not disturbed. Projections or bosses (C, Fig. 1) are cast into the carburettor bodies alongside the mixture screws (B, Fig. 1) so that when the tamperproof caps are fitted only limited rotation of the screws is possible. The illustration (Fig. 1) shows the correct installation of the caps whereby the screws can only be rotated in a clockwise direction.

4. ACCELERATOR PUMP STROKE Adjustment of the accelerator pump stroke is not normally required. However, it may be necessary to check the operation of the pump if a "flat spot" is encountered during initial acceleration. Therefore, if subsequently it is necessary to perform a checking/adjustment operation, it is to be carried out as follows: a) Invert the carburettor. b) Open the throttle valve and then allow it to close slowly until the adjusted nut (A, Fig. 7) just touches the accelerator pump lever (B, Fig. 7). At this point a 3 mm diameter rod '(C, Fig. 7) should just slide between the throttle valve and the bar-

rel. 3. FAST IDLE SPEED The fast idle speed is controlled by a specific fast idle gap set between the throttle valve and the barrel. It has therefore to be adjusted with the carburettor removed from the vehicle. The actual adjustment is carried out as follows: a) Invert the carburettor. b) Operate the choke operating lever to hold the choke valve in the fully closed position and check the fast idle gap with a 1 mm diameter rod (A, Fig. 6). c) Adjust the fast idle screw (B, Fig. 6) as required, to allow the 1 mm diameter rod to just slide between the throttle valve and barrel.

c) If the gap varies significantly from the 3 mm dimension, adjustment can be made by moving the adjuster nul. NOTE: If the operating rod and adjuster nut have been crimped together, it may be necessary to fit new parts.

2. CHOKE VALVE GAP

The following checks ensure that the correct clearance exists between the choke plates and the air intake wall when the choke is applied. The choke plates are opened by the action of the vacuum controlled pull-down diaphragm. A thermal actuator, which consists of an electrically heated expansion element, limits the choke valve gap to a relatively small dimension when the engine is first started, but allows the choke valves to open further after heating for a certain period of time.

The throttle governor has replaced the function of the fast idle cam. a) Check length (X) of compression spring and if necessary turn nut (A) to obtain a length of 23 mm (Fig 3). b) Pull off vacuum hose from governor and plug end. The starting speed should be 1800 ± 100 rpm. c) If necessary decrease speed by turning screw (B) in or increase speed by turning screw out. d) Reconnect vacuum hose to governor. On vehicles with automatic transmission, carry out the following additional checks.

• Air cleaner removed. • Cable from auto-choke heating element disconnected. • Auto-choke housing and bi-metal spring removed. Cooling hoses on housing remain connected.

2.3 Idle Basic Setting The basic setting of the idle adjustment will normally be required only in exceptional circumstances, such as after overhaul of the carburettor. I n such cases, the initial setting of the idle speed screw and jet adjusting screw should be carried out as follows: a) Lift and support piston clear of carburettor bridge so that jet is visible. b) Turn jet adjusting screw (8, Fig. 1) anti-clockwise until jet is flush with bridge (Fig. 7). c) Turn jet adjusting screw in 2 1/2 turns. This will give initial mixture setting. d) Finally adjust idle speed and CO level once carburettor is installed on engine.

2.4 Fast Idle Screw Clearance Pullout choke knob approximately 25 mm so that mark (F, Fig. 3) on control lever aligns with the fast idle screw (0, Fig. 3). Check that engine idles at specified speed. If not, slacken locknut and adjust fast idle screw.

Fig. 8 Piston and suction chamber k) Finally, reassemble suction chamber assembly to carburettor and refill damper reservoir with oil.

3. PISTON & SUCTION CHAMBER The operation of the piston and suction chamber on standard and ball-bearing type suction chambers can be checked as follows: a) Remove air cleaner assembly. b) Mark for location, then remove suction chamber, piston spring and piston assembly from carburettor. c) Unscrew damper from top of suction chamber and empty oil from reservoir. d) Separate piston, piston spring and suction chamber. e) Clean any fuel deposits off piston and sucti on chamber with petrol or methylated spirit, and wipe dry. f) Refit damper to suction chamber. g) Temporarily plug the two transfer holes in end of piston with rubber plugs or Plasticine (A, Fig. 8). h) Insert piston fully into suction chamber without spring. Secure large flat washer (8, Fig. 8) to one of the fixing holes with a screw and nut so that it overlaps chamber bore and limits upward travel of piston. i) I nvert assembly with piston fully down in chamber. Then holding piston, release chamber and note time taken until piston contacts washer (8, Fig. 8) should be: 5 - 7 secs - standard type 3 - 5 ~ecs - ball bearing type j} If this time is exceeded, check piston and chamber for cleanliness and mechanical damage. Replace assembly if time taken is still not within specified limits.

2.2 Idle Speed & CO Level Tamperproof seals (A. Fig. 1) are fitted to the idle speed (throttle) and idle mixture (fuel jet) adjustment screws to prevent indiscriminate tampering with the settings. If adjustment of either of these is necessary, the seal must be removed. Replacement seals must be fitted when adjustments have been completed.

2. IDLE ADJUSTMENTS 2.1 Preparatory Conditions • All other engine functions (valve clearances, ignition system) correctly adjusted. See 'Introduction'. • Induction system without leaks. • Ai r cleaner removed. • Crankcase breather connected. • Selector lever in position 'P' on auto trans. models. • All electrical components switched

off. • Test instruments (rev-counter and exhaust gas analyser) connected in accordance with manufacturer's instructions. • Oil level in carburettor damper reservoir at correct level (Fig. 2). Top-up if required with SAE 10W40. • Throttle cable disconnected at carburettor (A. Fig. 3). • Amb ient temperatu re between 15 250 C.

Specification: Idle Speed: - 900 rpm CO Control Level: - 2.0-3.5 % CO CO Setting Level: - 2.5 % CO Special Note: Engine inside CO Setting Level need not be adjusted. Engines outside CO Setting Level should be adjusted. a) Ensure: • Carburettor piston (A, Fig. 4) falls freely, when I ifted and released, onto bridge without any tendency to stick or bind. Piston should make a distinct 'click' as it contacts bridge. • Throttle valve/spindle moves freely without tendency to stick, and that over-run valve (A, Fig. 5) operates properly. • Cold start control lever (8, Fig. 3) makes full swing when choke knob is operated. With knob fully in, fast idle screw (D, Fig. 3) must not be in contact with lever cam (C, Fig. 3). If necessary, adjust screw per 2.4. b) Check idle speed and, if incorrect adjust by: Disconnecting electric cable (A. Fig. 6) from solenoid valve. Turning throttle stop screw (8, Fig. 6) to obtain 500 rpm and lock screw with locknut. Reconnecting cable to solenoid. Stopping and restarting engine to

open solenoid. Turning idle speed screw (C, Fig. 6) to obtain specified idle speed. c) Similary, check idle CO level.

Special Note: Always, immed iately prior to tak ing CO reading; run engine up to 1500 rpm, return to id Ie and tap suction chamber (8, Fig. 5) so that piston takes up correct position. d) If outside specified CO checking limits; turn jet adjusting screw (8, Fig. 1) to obtain the specified CO setting value. Turning screw in will enrich mixture; out will weaken it. NOTE: If more than half a turn of the screw is required to achieve a satisfactory CO value, the carburettor should be removed and serviced. After which the preceding checks and adjustments must be repeated. e) When the CO level has been set, readjust, idle speed and recheck. Special Note: Adjustments and checks must be made within 3 minutes of the thermostat opening. If complete adjustment procedure cannot be carried out within three minutes, run engine up at 2500 3000 rpm for about 1 minute before continuing. 2.3 Idle Basic setting The basic setting of the idle adjustment will normally be required only in exceptional circumstances, such as after overhaul of the carburettor. In such

Fig. 3 Carburettor details

Fig. 6 Idle speed adjustment

cases, the initial setting of the idle speed screw and jet adjusting screw should be carried out as follows: a) Lift and support piston clear of carburettor bridge so that jet is visible. b) Turn jet adjusting screw (B, Fig. 1) anti-clockwise until jet is flush with bridge (Fig. 7). c) Turn jet adjusting screw in 2 1/2 turns. This will give initial mixture setting. d) Finally adjust idle speed and CO level per Sect. 2.2.

methylated spirit, and wipe dry. f) Refit damper to suction chamber. g) Temporarily plug the two transfer holes in end of piston with rubber plugs or Plasticine (A, Fig. 8). h) Insert piston fully into suction chamber without spring. Secure large flat washer (B, Fig. 8) to one of the fixing holes with a screw and nut so that it overlaps chamber bore and limits upward travel of piston. i) Invert assembly with piston fully down in chamber. Then holding piston, release chamber and note time taken until piston contacts washer (B, Fig. 8). This should be 3 - 5 seconds. j) If th is ti me is exceeded, check piston and chamber for cleanl iness and mechanical damage. Replace assembly if time taken is still not within specified limits. k) Finally, reassemble suction chamber assembly to carburettor and refill damper reservoir with oil.

2.4 Fast Idle Screw Clearance Pullout choke knob approximately 25 mm so that mark (F, Fig. 3) on control lever aligns with the fast idle screw (0, Fig. 3). Check that engine idres at specified speed. If not, slacken locknut and adjust fast idle screw.

3. PISTON & SUCTION CHAMBER The operation of the piston and suction chamber on standard and ball-bearing type suction chambers can be checked as follows: a) Remove air cleaner assembly. b) Mark for location, then remove suction chamber, piston spring and piston assembly from carburettor. c) Unscrew damper from top of suction chamber and empty oil from reservoir. d) Separate piston, piston spring and suction chamber. e) Clean any fuel deposits off piston and suction chamber with petrol or
