At the top of the shaft, there is a splined area where the mechanical advance plate for the springs mount to. The top piece is able to pull down a very small distance, probably about 1/16th of an inch. I don't think it has moved from its original orientation on the splines but I am worried that it might come loose. I ran some high strength red lock tight around the area but it didn't work. I cleaned it again and put some more lock tight on it so hopefully, it will work this time. Is this top piece welded or just peened over on the top? I could hit it with the welder if that would lock it in but I don't want to do any damage to it with the heat.
