So i bought a mini bike a few days ago. It has a Tecumseh engine on it and for some reason i cannot get it to stay running. It starts on 1 pull but dies out a few seconds later. I tried giving it some gas in that few seconds that it stays running and there was absolutely no responce from it at all. Clogged Carb? Also, the kill switch is no longer there, there is one green wire that hooks up to 2 spots on the engine and runs up to the handle bars. At the handle bar end of it all that is there is a flat round piece. It's not connected to anything else. Could that be the problem? Please help me.
