The fuel can in front of the engine is not how the instructions would have you mount it. It won’t fit with the engine in the forward position, unless you turn it sideways. Also, there’s no definite location point. The belt on the supercharger (blower) is plastic and snapped right on. No mention of it in the instructions. In fact, in step 1 you’re told to use string to make a belt, then in step 9 you’re told to use a rubber band. The ‘C’ notch in the front of the chassis is so the belt drive can fit when the engine is in the forward position, however, I still had to thin it greatly to get the engine to fit.
