I was given a friends MSD ignition system. It seems to work very well. However, I have been having an issue with the rig if it has been running a long time (over an hour). It begins with a stumble over 55mph. If I push it and keep driving, eventually it will stall and it takes over an hour to start it again. I am nearly convinced the issue is vapor lock...but, thought I would have the ignition system looked at just in case. Nobody I have called has the ability to "diagnose" an MSD ignition or coil. On a side note, even AutoZone can hook up to a stock ignition and tell me if it has failed...
I have been happy with the ignition system (considerably better than stock); but, where can I have it inspected? I called MSD and they want $85 to inspect it (and another $10 to inspect the coil).
Put spark plug in one of the wires. Grab plug with hand. Have some one crank motor. You will know real fast if you have power to the plugs.
Careful boys, he may try it. Only probably is we wont be able to watch.
You do need to determine if it is fuel or fire when it quits, the advantage of it not starting for an hour is it will give you time to test everything. Install a clear fuel filter up near the carb and when it quits look at it, if it is fuel the filter will be fairly empty.
Careful your character's showing
The rig is down right now (working on coating the inside of the tub and some body stuff). I was hoping to have it running reliably when I get done...I would prefer to have it as a daily driver again; but, it needs to be reliable. I miss driving my Jeep...
