Finding TDC

^checked it like 4 times and same place.
Got it timed now. Freaking MSD E-Curve dist. is not an easy thing to use. Finally got it idling at around 18 adv. and all in at 33-35* by 2500.
Stumbles off idle though, I've got vac. adv. on it just not a whole lot, do I need to add more vac. adv.?
