choke needs adjusting and/or a vacuum actuator not working..in short must be the choke valve not opening fully...should be fully open of course when engine is at operating temperature..some linkages could need bending to adjust them also...

Engine idels at 3000 rpm after replacing carb and vacuume lines with new parts.


There should be an idle speed adjustment screw near where the throttle linkage connects to the carburetor. Turn it CCW a number of turns until the speed drops down. Make sure the choke has completely released before making this adjustment. Hope this helps!

I just rebuilt my F-150 1 barrel Carter carb (1985)once started runs great under all power ranges.Problem? Hard to start.


should adjust the butterfly to about 3/8" opening at 50 degrees farenheit when engine is cold. Usually about 1 mark to the lean side on the choke spring housing. If unsure set the choke to the center mark than richen up one mark at a time until the engine starts and idles up when cold after properly setting choke by fully depressing and releasing the accelerator before cranking. If it doesn't idle up enough turn up the fast idle screw 1/2 turn at a time. Another common problem with the YFA is the choke heat riser tube rusting off at the manifold and the choke not unloading when the engine warms. Install a new riser tube after using a drill bit the same diameter as the tube to drill out the remainder of the old tube in manifold before inserting the new tube and attaching to choke housing.

Sounds like the warm start choke. It positions the carb butterflies when the car is warm and adjusts the fuel mixture.

I wanna know if the 1985 mustang gt 5.0 ho is electric choke or manual choke


Electric choke from the factory,the choke pull off runs off of power from the alternators stator post which supplies about 7 volts when its running.Spring tension and a stomp on the throttle set it.
