Tyler, the 24 is my favorite mower, they will tackle anything. Yes I just use a 3 sided hone with 75mm stones so they don't drop into the ports in the barrel. I don't bother with the barrel if the scoring is deep, that will require a rebore and new o/s piston and that becomes cost prohibitive. He would be much better scratching around and picking up another FC mower and pull the motor off that. They still turn up on ebay etc for a few dollars. I sold 15 FC mowers last year for $10 each to a member here.
