I don't have any, but a retired friend of mine has two similar to it. One is a 14 HP cast iron Kohler, which is what your photo appears to be. The other one had a 16 HP cast iron Kohler and the quack machine shop ground the sleeve off center and ruined the engine when it was re-assembled. Caused the thing to throw a rod. It's in a pile over in the corner of his garage waiting on me to haul it to my garage and put it in another corner! I'm in no hurry. I've noticed that those old Kohler's (and I've got a K-14 HP with the external coil on my log splitter) which is giving me a fit trying to keep it running. I've done about everything I know to it and still it won't stay running 3 minutes. The charging coil has gone kaput as well. They're tough, heavy old tractors when they're running right. I have trouble keeping this FORD that belongs to my friend, in tune. Just vibrates out enough to knock off the mixture and make it run rough.
