most if not all of em will take a 3/32" allen wrench in the nipple for the RATE. CCW slows the rate amount from an amount of in hg to get the adv to kick in/get started & you can solder slivers of feeler gauge on either side of the arm so the notch will reach the end of its travel sooner or drill a mini hole in the arm & add a horizontle pin to limit the TOTAL. I would suggest dialing in the initial/total/springs before even plugging in the can. Rotor phasing may have been causing the issue as opposed to too much timing added from the can. A hand held vacuum pump is a good tool when working with this. I would reduce the lower shaft axial clearance to .005" (speedway mtrs has a good kit of FLAT shims for $10). check lower tang to intergear notch for rotational play (want near zero), by twisting the rotor back & forth slightly (just not enough to get into the springs) & get the NAPA Echlin MO3000 rotor with a .060" longer blade ($8.xx out the door) or drill out the rivet & make your own. get a brown or black cap with BRASS terminals.
