Anyone familiar with, or know where I can get parts for an overhaul? I know the engine is a 2-cyl Shwindawa(I think it's spelled right). I'm doing the overhaul for a friend, he's owned it for 20 years but has nothing on it.

 

Should be able to go to a NH dealer and get it.If not try Clevite overhaul kit you should be able to get that if not the OEM overhaul kit.Try a few dealerships otherwise IDK where you shold go.
