when its running at cruising speeds it seems to run fine....but when at a stop sign it looks like it loads up on fuel...black smoke...hesitation...couple blips and it clears......my fuel PSI is 5psi, Im thinking its all in the MSD....but i want to make sure my carb isnt the prob....it did this same prob with the old carb also..but it was sooo much worse....now i can drive it....but i want it to be reliable....
