Yes there were Craftsman & Sears power equipment powered by Tecumseh engines...tons of them. I have a few removed from old reel lawn mowers and some snow blowers too. Somewhere either on here or thru Google there is a cross reference or decoder to tell you roughly what year they are and it'll breakdown the other specs,like HP & crank info.
It's been a while since I did that,,but I do remember it was somewhat of a pain lol
