The problem often is that the that the return springs on the carb shaft get
weak with age and fail to return the throttle shaft all the way back to the
stops. Mine did this only when the car had been driven for a while and
things were hot. You may be able to wind the return spring tighter on the
carb shaft. I added a short throttle shaft lever to my shaft between the
two carbs and added an auxiliary spring from the lever end to the
carb-to-carb fuel line. The extra spring now always pulls the carb shaft
all the way back to the stops at idle.
Vroom vrooom,
