I have one of those engines, I like the Tecumseh engines. They look the cleanest. I was trying to run the engine with-ought the fan shroud, it has plenty of cooling fins. I was looking at your flywheel and it looks like it would be easer to cut the fins off the newer ones so you could run it in the open, I love the big chrome flywheel on the Mustang. I like the ignition inside the flywheel and the cooling fins are in tact on the inside of the cover, to me they look like the engine for the Mustang bike, it had the carb and the pipe out the front. Have fun, Dave
