I'm hearing a high-pitched whistle around my carb which I assume is a vacuum leak. i recently replaced the carb, cleaned the carb mount, manifold, etc., placed new gaskets when re-installing. I tried spraying WD40 around to see if I could locate the exact point but no luck. I assume the most likely source is the gasket/carb area, and that I need to pull the carb again (aarggh) and place new gaskets. Does this sound right? I sprayed area around vacuum to distributor and at PCV hose with no change in noise/idle, so I assume this isn't it.
