i have a edelbrock performer 4-barrel carb with vacuum secondaries. When i hit the throttle it sounds like my engine is whistling. I dont really know where the sound is coming from but i think its my carb. Can someone help me? Thank you
from what i know it is a bad gasket on the carb. an easy way to find out is to spray a liquid of any sort that will not hurt the engine at the base of the carb and if it sucks the liquid in change the gasket. that should fix that problem
get a piece of hose and stick one end near your ear and run the hose around the baseplate and intake and around all fittings at idle. the noise will jump out at you even if you can't hear it at idle. This is better and safer than spraying carb cleaner all around. a mechanic's stethascope with the metal probe removed also works great
A friend of mine had the same whistle on his built Pontiac 400 with a Carter carb. We checked and checked for vacuum leaks, but couldn't find any and everything ran fine. He REALLY liked the whistle for some reason.
