I have replaced the Alternator/Stator on my Spirit of 76 cadet. It is a new style Stator and I had to grind the casting to allow clearance for the change in the wire guide position. This was done per the instructions that came with the new stator. My question is about the aluminum cover that fits over the points and condenser. I will have to notch it to allow it to fit with the new stator. The question is do I actually need to cut and install the cover or can I leave it off?
