did the nutter bypass on my 99 yj. still have carter carb. had vac advance teed into ported vac on valve cover side of carb. ran pretty good but had some stumbling. today I decided to try and connect vac advance to manifold vacuum like it was pre nutter. it ran a lot better than on the ported vac. question is can I leave it like this or may I have some other issue? I have also done the team rush upgrade. still have stock coil.
