If the clutch stack is not aligned properly you may damage your start shaft. Typically the 8mm portion will crack due to stress from misalignment. Mount your engine and clutch stack into the frames as shown in the instructions. Leave all bolts lose at first. Next, tighten down the four engine mount tab bolt. Next you will want to check your main gear mesh. You can rock the engine slightly toward or away from the main gear to achieve a slightly better mesh. Once you are happy with the main gear to pinion mesh, tighten down the eight motor mount bolts to the frame. Once the engine is secured you can now check the start shaft for free rotation. Move the clutch stack slightly fore or aft until you feel the start shaft is free within the one-way clutch bearing. Tighten down the four clutch stack bearing block screws and you are done.
