I have decided to stay with 4cycle, and I have a rebuilt KPV about five years ago and only had 15 minutes to half an hour running time after the rebuild. I was told it was a Lynn Haddock built and previously owned personal engine.
Single Disc Horstman Dry Clutch
Engine does not come with any mount clamps or any pipe.
This engine runs great and strong.
The bore is .40 over
Horseman wet clutch
