[T2] High Idle

Yeah and the problem can be binding of the shaft in the body, or the external linkage.  The cad plating on some 32/36 also seems an instantaneous corrosion magnet, so the problem can even be an external one causing binding, or one with corrosion of shaft to body.  But I agree for sure with the thoughts presented, smacks of either cable/ primary linkage, or linkage on the secondary.  The quick jab lets the return spring pop something back closed a bit better than a slow letoff does.

     On progressive carbs, check that the secondary is closing all the way.  Especially if the carb has sat unused for some time, that linkage can become sluggish.  Only takes a tiny opening in the secondary throttle plate area to raise the idle quite a bit.  Closes with a snap but not when slowly closed is a classic symptom.
