Pertronix Flamethrower mechanical advance limiters not working correct.

Advance limiter don't work. Bronze springs (strongest). #6 Limiters. 18 degrees initial. Mechanical all in by 3100 RPM, results were 34 or 35 degrees total.This a normal combination.
So the #6 limiters let it add 17 degrees. They are supposed to add only 12 degrees!
I want to have 24 initial because the ignition box has startup delay parameter for easy starting. 24 initial and 12 mechanical will be perfect.

I just bought a msd but I thought I'd give it another try before pulling the petronix

The L shape straps which block the weights from splaying out don't work. Yes L straps stop the weights from moving out (kind of) but they don't stop the entire advance plate from continuing to move more. I tried to explain this to Pertronix tech but they denied that was the case even though I sent them video.
I stopped using the L straps and made new straps that go over both the spring pins. One end hole is size of pin, other side is short slot to allow advance I needed. It was trail and error to get length of slot correct to get advance amount I wanted...
I would suggest to send Pertronix back if you can and go with something else..

@@GreentweenVideo thank you for your response now I know I'm not crazy, my new msd arrived yesterday. It's just gets so disappointing throwing money at dream and it still not work. I'll pull the petronix let sit on the shelf maybe try it on another project someday.

Did you ever get it figured out? I have the same problem first total timing ended up at 52 degrees
