Let's take this one back to basics. If you're getting black fouling on the plugs, it's either excessive fuel or excessive oil. "Had carberator (sic) checked"...what's that really mean? if the float level's too high, your engine could be running rich, which would explain fouling the plugs...and fouled plugs would explain the "skipping," or misfire.

You say compression is OK [how many PSI per cylinder? Wet or dry? Or does "OK" just mean the compression is uniform, whether uniformly good or bad?]...but are the oil rings OK? Does the engine put out a blue cloud of oil smoke when it runs? And you say the exhaust manifold was checked for leaks...since the B has an integral intake and exhaust manifold, I'm guessing the intake was also checked for leaks--but if there was a manifold leak, I'd expect the cylinders to run lean, rather than rich. Was the manifold machined to insure that the surface that mates to the head is flat? If not, how was it "checked" ?

Obviously, someone's a great "parts replacer" on this tractor...you just need to get it to someone who's also a mechanic.
