I am experiencing fuel boiling problems after shutting off the engine.
Fuel boils inside the bowl and pushes out of the shooter right into the carb throat.
I do not think that any sort of phenolic carb spacers will be of any help, since the spacers I have now are fairly thick and do isolate heat enough.
I believe that what I need is a fuel return line to the gas tank.
Can anybody tell me or show me pictures of where I have to drain the excess fuel from to return it to the gas tank or back into the fue line?

Another new event with the webers is the exhaust popping with acompanying flames out the exhaust, which looks and sounds cool but gets tyring after a while. Is there anything to properly seal the individual heades pipes slipping into the exhaust?
