CARB TUNING
Before adjusting any of these screws run the car till the cooling fan comes on !
1. IDLE MIXTURE SCREW : ( Air Fuel ratio , A/F ) ( ON ALL MODELS )
The IDLE MIXTURE SCREW is located behind the carb in a hole . as you can see it marked in that picture .
To adjust the IDLE MIXTURE SCREW use a screw driver and turn it clockwise and counterclockwise until you get the highest RPM possible ! , after that press the gas to 3000 RPM to richen the Air Fuel mixture .
2. STOP THROTTLE SCREW SCREW : ( a screw with a plastic head )( all models)
This screw is just located above the hole of the IDLE MIXTURE SCREW see pictures below
2 different procedures for this screw !
PROCEDURE # 1 ( if you have the IDLE CONTROL SCREW in # 3 ) :
adjust the STOP THROTTLE SCREW by hand to the lowest idle possible ( counterclockwise )
PROCEDURE # 2 ( if you DON'T have the IDLE CONTROL SCREW in # 3 ) :
adjust the STOP THROTTLE SCREW by hand to the desired RPM ( 750 > 800 RPM )
3. IDLE CONTROL SCREW : ( NOT ON ALL MODELS ) ( I don't have it )
After adjusting the STOP THROTTLE SCREW to the lowest idle possible in PROCEDURE # 1 adjust this screw using a screwdriver to the desired RPM ( 750 > 800 RPM )
This IDLE CONTROL SCREW is located on the throttle bracket after the throttle adjustment nut , it should be in the marked area ( but as you can see i don't have it )
4. FAST IDLE SCREW : ( ON ALL MODELS ) ( Works in the cold morning )
This screw adjusts the RPM that car should rev at in cold mornings it should be from 2000 > 3000 RPM
this screw is really hard to find and reach , i just found it today !!! here is the area that it should be in !
you can adjust it by a screwdriver but you can only test it in the mornings ( don't mess with it if it is ok , & spray some carb cleaner to get better response in the mornings )
4. A/C IDLE SCREW : ( ON MODELS EQUIPPED WITH A/C ) ( Works in when A/C ON )
This screw adjusts the RPM when the A/C is on !
just adjust with a screwdriver , clockwise to increase RPM and counterclockwise to decrease !
i think the normal RPM is 1250 > 1500 RPM ( correct me if i am wrong )
any question ask me @ the forum ACCORD EX or e-mail me @ : honda_club_egypt@yahoo.com
