I dont know, I likemy 20HP OHV Liquid Cooled just fine though. I dont think there was ever a problem with it, except the one time the radiator got clogged up due to hard water deposits, but thats not even the "engine" really.
Ditto. I sure hope no one chooses other and says "Tecumseh". Man, them things deserve the name "Tecrapsy". My power washer has one, and my grandfathers tiller too. They have such a jerk-back on the starter rope! I've almost yanked my hand off so many times trying to start them things.
