As the title reads. This is a 23hp KAW that had approx. 2000 hours on it. The exhaust valve let go and did a number to the piston and the head. The head and piston are junk but other than that I think it can be fixed?? What do you guys think? Should I fix it or just buy a new motor. Dealer wants $1600 for a new motor (which I think is high).
