This image shows both the bare chassis, and the mill set up used to cut the notch for the carb manifold. You see, I failed to chess this thing out, and notice that the carb wouldn't fit inside the frame, so something had to give.br/ You can also see how many notches were necessary to get the engine to fit.br/ I should add that the 3quot; tube spine frame is actually the gas tank. Not kidding. The fuel will be pumped up to the carb with a vacuum pulse pump from a personal watercraft. The gas cap is the shiny thing on the right.
