I have a Farmall H that I hadn't run for several years. This summer I decided to get it out and do some mowing with it. The clutch was frozen, so i split it and replaced the clutch and all associated parts. It ran like a champ.
One day while mowing, it died. After it cooled down a bit, it restarted and went for a bit, and then died again. The next time it started it was running rough, backfiring, etc.
I assumed it was the carb. I bought a carb kit, took the carb entirely apart and cleaned and rebuilt it. Still no joy. I took it to a guy who does a lot of work on old tractors. He checked out the carb and said it was good. He found a couple valves were leaking pretty bad. I took the head to the head shop and had it re-done. Still no joy.
My magneto (Farmall brand) seemed to have a weak spark so I bought a new one. Still no luck. Mechanic thought the timing must be off, so he worked on getting the magneto timed to the engine. He claims the magneto timing and the engine top dead center never match like they should. Same with the old mag. He is pretty sure it is a broken gear in the hydraulic pump (I guess that connects to the mag???) Anyway, before we tear the engine down, is there anything else I need to be looking at. This was a great old tractor which is becoming a shed ornament.
Thanks,
Nate
