The flywheel-in-question is on a 1978 5 hp horizontal shaft engine... I stopped by a small engine repair place today and the guy was so young that he didn't have a clue about my engine not does he own the specialty tool...

BTW, nothin' broke today... Okay, I was trying to load some plastic food containers in the cooler and the sharp edge of one cut the back of my hand which bled like a stuck pig but nothing broke...
