I have an odd problem with a new MP distributor. It’s in a fresh 383 and is actually running well, but I spotted a possible problem. Unfortunately the distributor is the current model that is built by Pro-from/ China/ whatever. After the initial break-in of the motor, I pulled and opened up the distributor up needing to weld the T-bar (it had like 25° mechanical coming in. However, looking at the cap and rotor, the rotor appears to be running too high, essentially topped out solid against the top center contact of the cap. The way I can tell, the tip of the rotor finger is not where the arc is jumping from, its jumping from the top of the rotor finger to the BOTTOM of the cap contacts... the rotor has actually scraped away some of plastic from the underside of the cap. The contacts on the cap so no arc marks in the proper, outer perimeter location on the contacts.
I tried trimming 1/8” from the bottom of the rotor to no avail, it bottoms out on the top of the shaft up inside the rotor. Is there any way to shim the body of the distributor up in relation to the shaft?
