Kennedy 90 #1 Posted April 2, 2016 This is a 12 hp Kohler from a C-125 blackhood. Can anyone tell me what the black round object on the engine block is, and why would it be weeping oil while the engine is running? How do I repair this? Thanks Mark . 2 Share this post Link to post Share on other sites
bobert94 38 #2 Posted April 2, 2016 I believe its a welch plug for the gov shaft u should be able to clean it off and seal it with a sealer 1 Share this post Link to post Share on other sites
pfrederi 17,040 #3 Posted April 2, 2016 It is the reverse end of the governor shaft. Interesting I have 3 12hp in the shop. two have what I would call a welch plug (e.g. recessed a bit like my picture). One has what looks like the picture above standing proud of the block. 1 Share this post Link to post Share on other sites
