While I'm no Bull, Blueboy, CapeCodScooter, my thoughts are that you have an air leak. Have you tried removing then reinstalling the carb?? Perhaps check all the air connections from the carb out thru the hoses to their origin. Wish those fellows above would respond!!

You have a cracked intake manifold. You are probably pulling the crack closed when you tug up on the carb. Been there.

Would I see this crack on the outside ? What is that little flexible air hose line that goes to the air filter box? If I pull it or press tighter where it's clamped on that helps engine stay on at revs as well. Maybe just coincidence.

You will probably see it once you take the manifold off. To test it, spray a little starter fluid at the manifold while the engine is idling. If idle speed changes, you have a leak and need a new manifold as previously suggested.
