782 strange behavior

[Rmowl]

A 782 with a series II, starts up and runs well, pto engages,mows grass well. After maybe 30 minutes if I stop and turn off the pto, it won't re-engage. Next day when cold it will. It will continue to operate perfect until I shut it off, then that's when the issues start. If I shut engine off after running it takes a lot of cranking to start. I'm going to check the points timing. Not sure about the pto switch issue. I have a new switch just came in I haven't installed yet.

As for restarting the hot engine, I had same problem with my mag 20. After doing some research my conclusion was worn valves into the seats. I ended up rebuilding the engine. When I did take things all apart valve gaps were pretty tight..very tight.
You might start by measuring your valve clearance.
