Have you tried to move the rev limiter up to higher rpm or take it off and see if it still wont rev.


Does it just flatten out or does it studder out like rev limiter. Also do you have a soft rev limiter. Some will hold the engine at certain rpm without the poping and shutter of old style rev limiters.
It just flattens out.

If not use 1 light spring and 1 medium spring, this let the mechanical advance come in sooner. Does this MSD distributor with vacuum advance have a part#? I hope it ain't the cheap StreetFire 8362!
I am running dual springs that came with the Darts. My timing is at 35@3000 RPM. I have the MSD 8361 Pro Billet.
