Gas in oil on H

That tractor feeds by gravity and therefore the only possible way it could be thinning the oil, is by doing it while the tractor is running.

He just "thinks" it is running fine; it is either loading causing it to run way too rich or it has a cylinder missing pushing unbrunt fuel.

A few things that will cause this: 1. Needle/seat/float problem.
2. Carb enrichment problem (adjustment).
3. Choke problem or partially on all the time.
4. Dead hole pumping unbrunt fuel.
5. Engine running cold.
6. Bad compression.

Hope ya get er,

In addition to all what Allen and others have said, there is at least one other possibility if it is truly gas getting in the oil. If the shut off under the tank is not working, it is possible that the needle and seat are letting excessive fuel into the float bowl and the drain on the bottom of the carburetor is plugged allowing it to be filling so full of gas that it is leaking past the throttle shaft bushings, into the tube between the governor and the carburetor and into the pan.

If this is the case, I don’t see how the engine can start, much less run ok. Something here is not quite adding up.

I agree and the first thing I would be asking myself is why does this fella have to shut that fuel valve off?

Something is surely wrong and you've got to watch and listen to what the tractor is trying to tell ya. :>)

I presume that you live in Husker land, I'm curious as to where. I would appreciate it if you would drop me a note, e-mail is released.

Thanks,
