I believe I have the Governor and adjustment screw set right, and have the correct springs
installed, but it's still giving me grief. It starts easily, and runs strong at mid throttle, smoothly
increases rpm when throttle is pulled further out. Problem is that when I go to idle, it promptly
dies. It almost seems like it's running away at times. I thought it might be sucking some air, so
I sprayed carb cleaner at the intake manifold gasket. No change. Spraying at the gasket between
the upper and lower halves of the carb, at the front of the carb, caused a cough or 2. I was a bit
suspect about that seal at that point when I had the carb apart and reassembled. There isn't
a bolt there to suck the 2 halves together.
Could one drill and tap there, or should I try to seal it with something? If so, what?
The pic is from before I took the carb apart. Previous owner did have some sort of sealant
smeared on the gasket around the front of the carb.
