Karl, Thanks for the reply, compression should be find, because it has plenty of power when running. Fuel is fresh, checked the ground going to the starter an the one going into the black box at the back. Is there any kinda sensor that could shut the engine off? Oil, temp, anything? I took the airbox off and ran it until it shut off, while the engine was still turning I sprayed starter fluid in the carbs just to make sure it wasn't a fuel issue. Still shut down. Could a ground wire shut it off and allow it to start right back? Also it seems to run longer at an idle, still less than a minute. Thats why I thought it was running out of fuel. Thanks for the help.
