Hello, I have a Kohler Command 20 (Ch20S) on a Lincoln Welder (Ranger 8). Has 250 hours on it. Hadn't been used for about a year. Had always started great, but not this time. Realized the sun had gotten to the fuel lines. Replaced them and started and ran well for about 20-30 mins when I noticed what I thought was oil coming out around the stud holding the governor assembly. Shut it down and found the crankcase had fuel in the oil. Looked at the diaphragm of the valve -cover- mounted fuel pump and found it torn. Going to replace that assembly along with the crankcase breather/gasket located under the carb as well as change out the oil. My question is, will the leak around the governor stud go away or am I needing to replace some sort of seal on it inside? What's involved with that and how big of a job would it be? The stud has a little up and down play in it (maybe 1/16"). Is that normal? Any thoughts would be appreciated, thanks.
