Hey John H.,
I agree with John Schweibert, run it! Your test between wet and dry indicates you may have some compression rings sticking, but, that engine hasn&#039;t been run in some time, so you should consider that normal. If it were my engine, I would get some Rislone at the auto parts, and put that in the oil, then some Marvel Mystery Oil in the gas, only a gallon or two of gas. Then I would run it up to operating temp., and shut it off to cool. I would do this repeatedly for a day or two, then change oil and filter, because that stuff will clean out the sludge. Then run it with fresh oil and gas, don&#039;t forget the lead additive, and just play with the tractor, it is a really fun tractor once you get used to it. It should make it run better, and it beats tearing it down.
