Engine was used for 12 hrs stock then blueprinted by P1, new piston and ring, and added new large carb. Engine has 8 1/2 hours since rebuild. I was going to send for rebuild for next season but decided to go with a different engine. My son is overweight for Jr Tag at club races with this engine. Starter may need new brushes. Make an offer looking to offset cost of new engine. Buy it for $575 and I will pay for shipping. Will be in 2 boxes. 1 box for engine and 1 box for kit. Everything will be included except battery.
