sodbuster 1 #1 Posted June 1, 2013 I have a k321. the problem is an oil leak at the govenor. I replaced the brass insert (plug) and the metal sleeve behind the plug.I have the leak down to a drip. Is there a seal? I cannot find one listed.or do I need to pull the engine and replace the govenor rod assy. Share this post Link to post Share on other sites
rmaynard 16,363 #2 Posted June 1, 2013 I was just working on a K321 today that has the same problem. The owner had added a special crankcase venting system in place of the factory reed-type system installed by Kohler. There was no air coming out of his vent. We suspect that his problem has to do with improper crankcase venting. Other than replacing the brass governor nut, there is no seal for that area. If the governor is leaking, I would suspect that oil is also coming out around the points push pin. Check your vent to see if everything is installed correctly Share this post Link to post Share on other sites
MarkPalmer 81 #3 Posted June 2, 2013 Bob is likely right on this one, check to see if your breather plate is installed the right way with the metal reed facing the outside of the engine, small hole downward. Normally with it installed correctly, the crankcase is at a slight vacuum while the engine runs, so oil that flows on to the points pushrod and around the governor shaft is sucked back in. If the breather plate is backwards, the crankcase pressurizes and oil is forced out of those areas. -Mark- 1 Share this post Link to post Share on other sites
