Please Help With My Backfiring/Stumbling/Stall Problems

[spectras only]

FYI , I've run my 20' spectra for 26 yrs with the ancient point ign system with only one downtime.It was the breaker wire from the coil [replaced it 10 min ].Now my buddy runs it with the pertronix ignitor and experiencing similar problem as Hallett19. I've removed the cap and found the pertronix reluctor causing the rotor to be sitting too high on the distributor shaft and causing the rotor to be very sloppy with the retainer spring clip in it being too light, further causing chipping the corner of the rotor by hitting the posts.I'm not saying this is the trouble for sure,but would make sure the rotor sits firmly on the shaft. The reluctor can be machined on the inside to let the rotor sit a bit lower to get the wobble out.Some retainer springs [in older rotors] are firmer than the new rotors have nowdays.Just my .02 cdn Ps; my MSD system works great , but the minute it gives me problems I'm converting to magneto

It seems ok for the time, but I am sure that's what was eating it away.
Wow....so where is Pertronix on this whole deal..LOL
