What did I do? Help?

This is insane.
Bump stopped piston. TDC is where it belongs.
No crossed ignition wires I checked twice but I never removed any to begin with just moved cap assembly away to remove dizzy.
I know about welding up the slots. I posted earlier the plate isn't even in it anymore.
Set crank at 10' BTDC on compression stroke. Set rotor pointing to #1. I have done this a million times before. Car starts fine then dial in timing. Not this time. Engine barely starts runs terrible coughing and dieseling until I crank the dizzy a ridiculous amount to smooth out. Timing reads approx. 25-30 ATDC. I know it sounds like I'm telling you all 2+2 equals 8. :BangHead:
I tried a spare dizzy with same issues.
I tried a different ECU.
I tried dizzy 180 out. Won't start and pops carb.
I reversed polarity of dizzy (Not that)
I've used 2 good timing lights
Pick up and reluctor align with rotor pointing at #1 plug on cap.
Springs are in place.
VC in proper hole on plate.
I've yet to try a different cap and rotor but can't see it being the issue as it runs smooth.
I even tried hooking timing light to all wires to see if any of them would go to BTDC without success.
When running I can rev it up and timing will advance in the right direction and go to about 25-30 from 50 ATDC.
I would be scared to death to rev it up and try to set timing to 34 BTDC in fear of breaking it or bending a valve.
I drove it without the VC hooked up and runs great.
I will try and get my buddy over to help video to prove I'm not nuts.
Have you inadvertently attached the vacuum advance to manifold vacuum? That would explain why it runs ok with the vacuum can disconnected.
