Completely stumped: High Idle Carby

[zoe60]

IDK intake flange is warped and distorting the carb butterfly shaft when you torque it down??? Interesting how the problem followed the NEW used carb. Out of ideas Scitzz-

Yeah, Maybe you could hook up 12V from somewhere else for an experiment.

I have the same problem on mine. I have been trying to figure it out for a while now. Please let me know if you find it. Thanks.

Try pumping gas pedal? When starting the engine I let it run for about 10 seconds and then press the accellorator to release the choke.

Assume you've tried the white plastic idle adjustment screw on the left side of the carb?

Oh yeah, I turned it until it does nothing, got it down to 2500. Revving it to let it kick down lets it kick down. You can see the little weighted piece move out of the way, then it idles at about 3K before sloooooooooowly dropping back down.

Tom kind of pointed in the right direction. I would call it the base idle screw. Missing on daughters Carb.


It is where I am pointing here.



Finagled a small screwdriver in there and dialed it down. Viola. Set the rough idle and rolled. Thanks guys!

If I hadn't been fortunate enough to have another Carb to pull out and stare at for a while, I would still be humped ...
