alright i got a vespa piaggio or somthing close to that name hehe, its a 78 i think. anyway it has the mechanism that you hit the switch on the back and the button pops out like Brandon Edge said. Me and my brother got it to turn over pretty easily but it won't fire up. You pedal it with the gas, choke, switches, and compression release all on, drop the compression release and the engine kicks in but it won't idle at all, by the time the moment from the pedalling stops the engine dies, any help would be apreciated.
