Tecumseh..PTOOIE!

I have also hated those nasty engines forever. Give me a good ole' Briggs any day. If it won't start, just get a bigger hammer. It will run with no rings. I once had a B&S that I cut lawns with for a week that would only run full out. I found out later it was because the throttle valve was gone. It had probably been sucked into the cylinder and blown back out the exhaust...but still running.
