i have a 2002 woods mid mount 25-60 25h.p. kohler with about 850 hrs on it. after about 100 hours like 1 out of every 20 times she ran after the temp was up to par i had a lifter pecking that could be heard a mile away and the only way i could hush it was to give it a shot of auto transmission fluid straight through the carb while it was running. might sound stupid to some but it is a godsend to any valvetrain by cleaning carbon. after that got old yours truly gave it a brand new set of lifters and that fixed it. by the way the lifters in it are small block chevy and most any will work. anyhow a couple weeks ago at only 840 hrs a magnet came out of the flywheel and thrashed the charging system. 200$ later a new flywheel and stator had me up again. anybody had similar problems?
