the turn on lead doesn't need to be high current, it should work all way down to 10v or so. all it does is tell the ignition box to turn on. the bigger voltage wire that he has running to the battery is what provides the ign the real power.
seems you have good ignition and timing.
you have good compression.
the only other thing needed is fuel right?
what is the baseline tune on the carb you have and how is the carb setup now???
Carburetor is a quickfuel super street series 680cfm vacuum secondary carb.
I’m running 65 main jets and 75 secondary jets.
.031 idle feed restrictors, .065 idle air bleeds, .033 high speed air bleeds.
A 9.5hg power valve with .049 pvcr’s.
Floats are set half way up the sight glasses.
Idle mixture screws are about 3/4 to 1 turn out.
This isn’t a fuel issue I know it’s ignition.
I keep thinking it’s the crane box but what’s throwing me off is how this missfiring clears up once I take away the vacuum advance.
So that leads me back to rotor phasing.
But I have checked rotor phasing and it’s good.
So this is very strange I just don’t know what’s causing this.
