IHC IH Model M 1-1/2 HP Spark plug throttle governed engine.

I picked this one up as a parts motor, missing many parts. Bought a WICO EK mag online, fabricated a governor rod, rebuilt the mixer new suction tube and needle valve. New rod bearing. Replaced other missing parts I had in stock. This is not a Hit & Miss engine it is throttle controlled by the governor. Completely different operation. Have it running slower now, you can here it throttle up to fixed operating RPM when the governor kicks in.
