Another quick vacuum advance question
So i just got done installing a motorcraft 2100 and a new air intake on my 86 258 t176 i havnt done the nutter yet. I bought it all from gronk the guy on ebay. Ive seen some complaints about him I didn't have any problems id buy from him again. But anyway. Im down to fine tuning it. Ive fond that the jeep runs awesome with the vacuum advance unhooked. When i hook it up to the port on the carb it stutters and there's a small pop coming out of the exhaust no matter how I tune it. Should i try to hook it up to the manifold vac and re-time it. Or can i just leave the vacuum advance off without destroying the motor. its not a daily driver so the only concern i have is the life of the motor not gas mileage. Im definitely not a mechanic so maybe someone with more experience could help me out.
