Found that my distributor vac advance was leaking and the weights weren't working. Got a rebuilt one and it made the car run terrible. I took the triggers out of my old one and put them in the new one, got new point and condensor. Everything seems to be working on the dist. now but it run like crap! It will hardly idle and when you time it to 27* it runs very rough and won't idle.

Which engine, which distributor, and what's your timing procedure? It's not the same for all engines/years. You also need to be sure you've got all of the vacuum connections in the right places.
