the engine looks real clean but i cant say for certain it was rebuilt, its got what appears to be the original carb which is also very clean. i dont know why the engine is using an external coil this is the way i got it. the second spark plug hole is fine, just capped but unscrews. it will come with the exhaust manifold as seen in the pics. i also have a 150CC with phelon ignition which appears rebuilt and ready to install the barrel and new piston the serial begins with an "h" on that engine. if there is interest, ill sell that one also. id like 1300 for that one.
