I believe I have a locked up motor will look farther into it this weekend: just bought it. thought it was a head gasket but put a battery in it and I hear the solenoid and starter kick and motor trying to move but doesn’t. I was told it had a new jug put in and gaskets it was running but then it stopped and could not get it to turn over I took the spark plug out and still could not get it to turn over so checking my options out
