So am I using the G4 body or the LM body? I guess I don't have much choice there as when I was removing the G4 from Goliath it didn't want to give it up so easy.So when I was removing the air line for the Decompression vales that part broke of the carby.I didn't get it out of the hose in any usable condition.So I hope you mean use LM as I have no G4 body's at all.
