Mark Mark, so just so you have the most current information, I got rid of the cylinder head that came with a 19.5 horsepower OHV engine. I blew the spark plug out twice. I don't want to have to rethread it. I got a problem with the threads on one of the valve cover threads also. So I happen to have a 14.5 horsepower ohv engine. The cylinder head matches up except it doesn't have extra material around the exhaust area but it seems everything else lines up. In fact, I was using that tonight and the ignition turns the flywheel but the flywheel does nothing except spin so that's where that's at. I got to check on the pushrods that are from the 19.5 horsepower OHV engine to make sure they're the same length as the pushrods that I'm not using from the 14.5 horsepower engine. And I definitely had spark using the spark plug tester. So tomorrow I got to figure out why the flywheel is rotating and there is no engine starting. I actually made a video of what happened tonight.
