I searched this forum and believe I am looking for a fairly substantial vacuum leak.
Anyone have experience with this?

I employed my un-patented "Jamesp Extreme Super Smoker" which runs on cheap cigars, which has become my current aroma. The leak is on the forward right corner of the engine under the manifold in front of the vacuum reservoir. I cannot see the exact point of exit for the smoke though. Any thoughts on how to proceed?
