This engine had a 1" x 3-5/32" shaft, 9 amp alternator, and a fuel pump. If you have an electric clutch, you will have to purchase an engine with a 9 or 16 amp alternator or use the stator and regulator off of your old engine. If you have a fuel tank or fuel pump mounted to your engine, you will also need to use it off of your old engine or purchase an engine with those features.
