Ok finally bought a motor for the green monster. It is a new Duramax 16 hp. I have already cut the crank and added the adapter and put on the clutch of the 295 robins engine. I had to take the clutch apart and clean out all the rust and get everything moving in it again. Slides pretty easily now. Started the engine and it shuts at idle after a second of running. The belt I bought needs to be about 6 inches shorter.
I need to cut a hole in the metal panel for the air filter.
