I charged up the battery, tried to start it, no go. I checked compression on both sides, good there too. I took off the starter, connected it straight to a battery and it spun great. It is a new starter, because the old one would not turn the motor over very good. I put the new starter back on, and I got a car battery out and hooked up direct to the starter and again the motor only turns over very slow. Next I removed the heads and valve spring covers to see if the valves are working right, and it looks like they are working like they should. Even with the heads off (no compression) the motor turns over very slow.
What is going on I don't know. I had the Onan in my first Case tractor rebuilt, and that was expensive. I really don't want to do that again. If I can't get the Onan working again, I may try to see if I can move the valves on the Case (the valve for the tiller and the holding valve on the side of the tractor) over to the Massey 316. Or just part it out.
