Cracked head
Dad has a "100" assembled from more machines than a Johnny Cash Cadillac. It has a K181 Kohler in it. Been a long time since we ran it (governor issue). Carried it to the shop today and got it running. Noticed it appeared to be blowing by a head bolt, smut all over the head between the plug and the bolt.
Figured blown gasket, no big deal. Pulled the head off to clean it up. Wire brushed the carbon and found this. Dad couldn't ever recall seeing a Kohler head split. FWIW, the spark plug hole has been Heli-coiled, maybe some damage began there? Upon inspection, it appears I milled this head down at some point many years ago. Anyway, gonna be shopping for a used head. Need to look into a clutch disk as well.
Who else has seen a Kohler, or any other air cooled engine, split the head?
