Default Re: Loud Whistle From 94 Carburetor

Someone told me once that he used a propane torch to track down a carb. whistle/air leak.
With the engine idling crack open the torch without lighting it.
Pass the torch around the suspected areas of the carb.
If the idle goes up then further pinpointing should lead to the source of the leak.
