I got this engine with some karts and parts I bought. The engine has a 1985 case according to the serial numbers. Has a motor mount attached. Has dual pump around fuel system. Ignition is all attached also. I looked in the exhaust port and the piston looks good. Reeds also look fine. Engine turns over and has compression. It was raced at some point because there is paint on the cylinder and case similier to what they would put on in tech line. Has engine gear attached. I took the Mikuni carb off and cleaned it. All the jets and ports look fine. All you need to run this is a pipe and air cleaner.
