I'd be glad to pass on what i can, Sanfelice. I had three problems:
1) Air chamber gasket was leaking -- gas would seep into the air chamber (main carb plenum). Solved by buying a new OEM gasket and putting it in.
2) external leak from carbs -- wrong type of fuel seals/o-rings in the carbs, where each carb joins the plenum. I took the old seals which were in good shape from my other carb set.
3) Incorrect float setup in carb #1.
I hung a large funnel from the rafters in my garage. The funnel has a shut-off valve on the spout. I connected a clear piece of 1/4" tubing and ran it into the fuel inlet of my carbs, which were off the bike, resting on a bucket. By letting gas flow into the carbs, i could see whether the gasket in the air chamber was leaking gas, look for external leaks underneath, and also manually operate the float in carb #1 to see if the float valve was leaking when i shut it off by hand.
Hope this helps!
