Hi I'm from London, I have a 183 air cooled typh vespa. It's been a pain in the ass. The other day rode to the petrol station, put some petrol, came ouot and opened up the throttle. The bike started accelerating automaticallly, then the next day bike doesn't want to start. Any ideas guys. Checked for spark and there is petrol making it's way to the carb. The inlet manifold is worn but the bike has been running fine. Any ideas? Andrew
sounds like a carb problem, has your air filter came off, i say that because when i two stroke runs lean it revs on its own, if the air filter came loose it would run it lean. if its not that i would strip your carb and check for blocked jets
