Removed all the shroud's around the genset on Sat to see what I could get too. Framing and spare tire had to come out also. After extensive research and multiple calls to people that work on small engines and gensets no one would work on one in an RV. I did not pull head because I could not find a head gasket or internal parks for this 25 year old genset they all say discontinued. Still waiting to hear from the Kohler rep he was not working Fri and Sat. Thought maybe I could get to an access cover to check cam shaft but could not. Someone suggested maybe the internals of the muffler collapsed clogging the muffler, found no rattling inside and when I cranked engine over the exhaust sucked my hand in instead of blowing it out. Also air and gas are coming out of intake instead of sucking in. Almost like in was running backwards.
