It's a 1-jug 16hp verticle shaft on a Wheelhorse. Blew white smoke twice,
sputtered and then kept running normal. Now chokes black smoke and fouling
the plug. A mechanic said something about a seal accessible from the
bottom, so I pulled the engine and saw no sign of leaking on the shaft seal,
and the oil pump/filter O-ring looks good.

Any ideas? I've good compression and the carb appears to work fine. This
came on suddenly.




check the intake valve adjustment.
