Can't adjust ignition timing any further
I've got a B20b that I convered to OBD1 with the intake manifold, dizzy, ect all from the old LS motor.
I put the gun on the crank and the red dot lines up with the mark on the timing cover a 5 degrees BTC, I tried to move the dizzy back and I can only get it to around ~ 12 degrees BTC before the dizzy maxes out on the sliders.
I changed the timing belt and water pump on the motor and made sure to double and triple check the timing when I did it, everything lines up and nothing is off.

Re: Can't adjust ignition timing any further
No everything is fine, I found this out:
And figured out I was doing it wrong since my gun is adjustable.
If you use a non-adjustable light, then you use the red/brown markings on the crank pulley to set timing since it's basically direct-read. If you're using an adjustable light you're supposed to use the white mark since the light will delay its pulses to line up with the white mark based on how much timing advance/retard you dial-in to it. If you're still confused about it, just set your light to 0 and use the marks on the crank.
