The only thing he put on was his carb he had bought. It happens.

Don't want to beat this dead horse too much further, but my motor was not a lemon, the builder was a lemon. There were more tolerances in the engine out of spec than in spec! The most basic rules of engine building, that you would follow yourself in your own garage, were not followed. As Camcojb said, avoid them.
