My mower just went kaboom, literally. A large chunk of metal went shooting out of the side as I was mowing my yard. I really like the mower, and a similar replacement would be around $300. Does anyone have experience with replacing a mower engine? It's a Craftsman self propelled mower with a Briggs&Stratton 6 hp motor. I've found several places that sell a short block for around $150, which is fine, but I've also seen several places that sell complete new 6.5hp motors for the same price. I'd rather just plug a new motor on there if possible, but I don't know about compatability issues. Anyone have experience with this sort of thing?
