Yep.....its a stock dizzy.. OK... I will lower the idle a bit...I think you guys are right I'm running too rich as my tail pipes have black soot instead of brown on the insides. It starts right up and did not backfire through the carb just the tail pipes and in quick sucsession upon deceleration and hill climbing at aceleration..... If I advance the timing I should be closer to tdc..agree.. how close can you get less than 5? What about vacuume at idle I thought 17-19 were good numbers at idle? Would it help to have a vacuume gage in cab and see what happens while running around. I can run a hose from wiper port to a hand held gage..what would I look for? THANKS or your advice I still need help... Steve
