Reinstall carburetor on engine and reconnect all vacuum hoses.
Reinstall throttle opener bracket on carburetor.
1986 HONDA ACCORD LXI INSTALL
Remove throttle opener bracket and install mixture adjusting screw hole cap. Repeat procedure until idle RPM and enriched RPM are correct. Run engine at 2500 RPM for 10 seconds to stabilize mixture. Close propane control valve and recheck idle speed. If enriched RPM is high, enrich mixture by turning mixture screw counterclockwise 1/4 turn and recheck RPM.ġ5. If enriched RPM is low, lean out mixture by turning mixture screw clockwise 1/4 turn and recheck RPM. Disconnect and plug vacuum hose from intake air control diaphragm. Start engine and warm to normal operating temperature. On 1.8L and 2.0L, install carburetors in reverse order of removal and replace coolant, if required. Grab head of screw with a pair of pliers and remove hole plug.ġ3. Drill through center of mixture screw hole plug. Place a drill stop on a 1/8" drill bit (1/8" from end). Disconnect throttle cable and vacuum hose from throttle opener diaphragm. Label and disconnect all vacuum hoses and lines from carburetors. Remove nuts from air screens and flanges. On 1.8L engine, drain coolant and remove carburetors as follows: Remove two 10 mm bolts under air cleaner base. Reconnect vacuum hose to fast idle unloader.ġ0. Reinstall bracket and reinstall carburetor on engine. Remove mixture adjusting screw hole cap from behind throttle opener bracket. Remove throttle opener bracket screw and bracket.ĩ. Lift carburetor clear of studs and tilt it backward. Remove carburetor nuts and washers, and bolt securing steel vacuum manifold. On 2.0L engine, disconnect vacuum hose to fast idle unloader. If engine speed does not increase, close propane control valve and remove air cleaner.Ĩ. If engine speed increases to enriched RPM, proceed to step 15). With engine idling, slowly open propane control valve to obtain maximum engine speed.ħ.
Insert propane hose 4" onto air intake tube. Disconnect air cleaner intake tube form air duct. On automatic transaxle models, disconnect hose from frequency solenoid valve "A" and connect it to bottom port of air control valve "A". If idle speed is extremely high, check dashpot system. If necessary, adjust idle speed to specification by turning throttle stop screw. Keep front wheels in straight-ahead position on models with power steering.ĥ. Connect tachometer and observe idle speed with all electrical accessories off, including electric cooling fan. On all other models, disconnect and plug vacuum hose from intake air control diaphragm. Adjust idle speed to 650-750 RPM (600-700 RPM on High Altitude) by turning throttle stop screw.Ĥ. Adjust idle speed to 650-750 RPM by turning adjusting screw on controller motor. With engine idling under no load condition, turn A/C on. Adjust idle speed to 50-650 RPM by turning adjusting screw on controller linkage. Turn headlights and rear defroster on, and set heater blower switch to maximum output. Adjust idle speed to 550-650 RPM by turning idle control screw. With engine idling under no load condition, lower idle speed as much as possible by turning throttle stop screw.Ģ.
On 2.0L engine with automatic transaxle, remove air filter from frequency solenoid valve "C" and plug the opening. Start and warm engine to normal operating temperature. This would not affect the high idle nor increase it.ġ. At least it should keep engine from stalling. There seems to be more than 1 possible causes and I would suggest adjusting the idlng speed first. Problem seems to be linked to the autochoke which Was anything done prior to this occurring?
