I have an 81 D150 that i converted over to electronic factory ignition and ever since i changed the distributor its always had a miss. Ive tried timing it to the factory specs of 16 degrees and it will run fine until i hook up the vacuum advance then it starts to miss again. When its hooked up to the vacuum pod it advances the base timing of 16 degrees to about 20-30 degrees causing it to miss. Ive timed it witht he vacuum line hook on and off like your suppose to do and it will run fine both ways until you try to drive it. I dont know what is left to do because the valves are fine and the plugs and wires are right. Any help will be appreciated.
