Well, I should have specified that its defiantly engine related, may just be bad timing as if you recall some months back helping me with that. Nevertheless the stutter comes at about mid throttle range kind of a pop, pop cough stutter. I can pretty much produce at will, I really thought it was a carburetion issue either starving for gas, or too much. I think the new dizzy may help me a lot and will also probably cause me to have to go back to square one and retime everything again. The stutter is just that hesitation , it can be felt while your driving but just really as a stutter not really any u-joint or drive train that I can tell, and since I can produce this at idle while sitting, I almost have to think it’s a timing, carb, or vacuum issue?
