i fooled around with this mod today in the school parking deck

and it seems to have worked... i dont really know how to explain it but something just feels smoother about how the motor pulls.... however i have to ask about whether i actually followed the instruction right.
After taking of the rotor i saw the hollow pipe that the rotor was screwed onto. I am assuming that this is what is referred to as the distributor shaft? There is screw about an inch into the hollow shaft. I was able to loosen the screw and the shaft came loose and i was able to spin it around when pulling it out. However when i pushed it back on there is a point where the shaft locks into a notch... i am assuming that the notch is just slightly bigger than whatever it fits into and because of this the shaft has a little bit of play. So by inserting the shaft and turning it counter clockwise, so that the shaft sits all the way against one side of the notch, I could tighten the screw down firmly and keep the shaft from moving around slightly in the small notch. Was this thinking correct? Did I do it right?
fyi you can't actually see this notch idea that i am talking about but as you spin the shaft around you will FEEL what i am talking about.
Let me know if im a dumb ass. Thanks!
