My dwell was too high and I didn't know how old the points were so I replaced the points and condensor,(I taught my son (it's his truck) how to do this as he had never seen points and condensor before) set the dwell at about 31 degrees, checked the timing and the truck runs quite nicely now. Had previous problems with hesitation, popping, bucking, and lack of power. Now about this grease cup. Does it pull off, screw off or...? Thanks
