Tim,
So far, all of the timing adjustments have been made with the engine running. The next step would be to remove/install the distributor again after confirming that #1 is at TDC by observing the valves on #1 cylinder.
I've already been to the mechanic three times to get the truck running right so thinking now would be a good time for me to learn how to tune and time the truck myself. The mechanic has given up on ignition timing and now wants to take the carb apart. The previous owner was very specific about making sure that the rotor lines up with the cap when the cylinders fire and had modified the cap to fix. Fortunately, I kept the old cap and will put back on the truck this weekend and see if it makes any difference.
I'm just bummed that my "new" truck ran great and now I can't even drive it because it misfires and sounds like it's running on maybe 3 cylinders.
Thanks again for your input,
Ron
