..... first... thanks for the help guys...... I may have found the problem!!
What I did is, swop the coils, to see if the problem would follow the coil.
and when I pulled the plug wire of off the #3 plug, the little metal boot that connects to the top of the plug, was still on the plug. [broken]
So, I am thinking,.... at low RPM's there is not a good connection [causing the miss].
just ordered, from Dennis Kirk the coil [just to make sure] and wires.
I did call Dyna [ignition], and he said, it is possible that the Dyna ign. could cause that problem..... I have had issues with it before.
and I have had the carbs. apart.
I should receive the new parts, Thursday. Thanks again [time will tell]
