Don't know if this helps anyone but I will post and see. My Craftsman lawnmower quit on me after just three years. Mower deck and wheels were fine but engine was toast. I made a pattern to see if a replacement engine from Harbor Freight would fit and it did. The vertical shaft engine was originally $149, on sale for $109, with 20% coupon $88. I bought it and paid the extra $20 for a 2 year warranty. Had to get a blade adapter as from Sears for $5 and throttle linkage from Home Depot for $7. For less than $125 I have re-powered lawnmower that has a 2 year warranty on engine. Mower is actually more powerful than it was when I got it new. Hope this might help someone save a couple of $$$
