Only runs 40 Degrees advanced

My posts about variable reluctance pickup polarity are not valid. I found that the dual sync, and hyperspark are both hall effect distributors. OP is not aware. I found on the Holley Sniper forum a question about difference between dual sync vs hyperspark distributors. Dual sync has cam type sensor too, an indicator for #1 sync for sequential efi and direct fire cop without rotor. Dual Sync vs HyperSpark
The OP started with dual sync, broke that, then purchased hyperspark. I think problem lies in step up, of distributor, wiring, phasing rotor. The link above suggests nobody knows....

Kit yes I am aware of that I did not need a duel sync but that was all they had when I put the system on so when that got ruined I bought a hyper spark and change the settings in my hand held for that. And since I was still having problems I put in my trusty MSD pro billet and changed and the hand held the parameters for that. I now have it hooked up for no timing control with the MSD controlling all the timing and the six AL only gives the sniper a speed signal so it acts just like a carburetor and it seems to be spot on.
Also kit I think it was you that told me to set it up at 13° with the reluctor just passing the knob on the coil and I did that. And I get the same thing every time I set up for normal timing like 10 or 15° it cranks and cranks and never fires until I turn it off then I’ll get a spark And it will try to run backwards for a second and blows gas and **** all over my hood. Now If I set it to 40° advanced it starts up perfectly fast idle warms up slows down I can rev it up it will restart in two or three cranks but just doesn’t have any power because if you drop it in gear it will die. So you guys know I am trying your suggestions. I think you also suggested that the polarity was wrong from the pick up I have not switched those wires because they are all keyed to plug-in a certain way and they are still all plugged in like they was from the beginning. You know black to black and violet Violet but I could pop a pin out of one of the plugs and switch them just to see because that’s what it sounds like it’s doing.
