I just got my Morini MO2 engine running for the first time, and I decided to check for air leaks. The idle is not very high, and it did change when I adjust the idle screw on the carb (Sha 14:12). However, when I sprayed some of the carb cleaner on the head gasket and the base gasket, the engine dies. This means I have an air leak right? But maybe just very minimal since the idle isnt high?
I used new paper gaskets when reassembling, but I did use the old head gasket. I will try the new aluminum one I got with the kit.
