Well I have been shutting the gas off and letting the carb run dry and then switch it over and it still revs up. I pulled the manifold off after running on gas and shutting down without going to diesel. I found gas on the walls of the manifold and in the head past the butterfly valves. It was wetter on the front two cylinders. I checked the aircleaner and it has no restriction. I checked the butterfly valves and they are closing fairly good. I put a shop vac on the head side of them and using a smoke stick, I have to have the smoke stick right at the intake for the vac to be able to pull any smoke in at all. My local service manager thought they looked good also.
Any thoughts on how I am getting gas in the diesel intake? I also believe the valves are all set correctly in the head.
If it is the buttefly valves leaking, how do you get them to seal up better? I let them find center and tightened them up already.
