Just wanted to add my two cents for the great service Ray does. I had a Nova Rossi Plus .21-5, that I had not used very much maybe a gallon or so, that would run erratically. I tore the motor apart and I could push the piston a 1/4" inch or so above the top of the sleeve. The only thing I could figure I was doing was letting the engine cool down with the piston stuck at TDC enlarging the sleeve. Anyway, I priced a new P&S and it was $210.00, almost what I originally paid for the motor. I sent the P&S to Ray, and I received basically a brand new engine. I followed his break-in and ran it all season and it is still running great. Do not hesitate to use him to your advantage and budget!
Thanks, Mike
