Distributor or MC2150

I am begining to wonder if it is my distributor not my carb.....if it is not allowing for the timing to be right when I try to drive it. After electronic ignition on a 77 Cherokee 360 2bbl can be faulty...don't know going through every scenerio to figure it out. HELP!!!!

You may have a vacuum leak somewhere this will make it difficult to time-n-tune.

No 77 listed in the link below, but between 76 and 79 you should be able to see where vacuum should be coming from. I suspect that if it's vacuum related that you are getting mainfold vacuum all the time instead of ported after warmup.

Doesn't the 77 have the Prestonolight distributor with huge plastic vacuum ball for the advance mech? If so the plastic ball is notorious for leaking and causing advance/driveability issues.
