I came across a brand new complete Onan P220 . It goes in a 1990 Toro Wheel horse mower but can be used in most anything I would think, maybe a sawmill ? ( 1 and 1/8th key way shaft )
This engine was kept in a climate control basement since it was bought new.
I don't have a clue what I will do with this but I like old engines and this 20 hp seems strong enough.
Will it be ok to run it a few minutes without exhaust pipes because I don't have them. I don't want to mess up these aluminum heads ? I removed the plastic plug where oil plug goes and put a new plug in it. Installed oil. This motor is ready to install in an old 1990 Toro Wheel Horse which I haven't found yet.
Were these engines any good ? This one was made in Huntsville Al and I was told that plant closed in 1997. It seems parts are still available .
