The Ford Barn

Dont do a lot of these but have had five in the last 90 days.
Common problems are shorted wire under the vacuum plate.
Most have defective vacuum advance unit.
These only have vacuum advance with no mechanical advance. Vacuum supply
comes from two ports on carb . One venturi opening is at the carb venturi and the other is from a transfer port slightly above the throttle plate. As spec chart shows vacuum is very low signal ranging from 1/2 inch of vac up to 4-5 inchs of vacuum.
Springs are mounted on eccentric pins allowing the springs to be adjusted. Both of the ones i just did needed some increased tension and wouldnt return to zero when advanced.

Yep , both of them are beautys !! The one had a broken , shorted lead with when vacuum was applied which probably caused your missfire...
The other unit was just rusted and crudded up, had to cut the shaft off it to save the housing. Looks good ...

The one that was tight to turn was on an aluminum timing cover and I couldn't get it out, so I removed the cover and broke the cover off with a hammer and then used Kroil to free up the shaft til I got it turning freely. I installed it on my car and drove it a few hundred miles and it developed an occasional miss, like a momentary loose connection, and I took it off and could hardly turn it again. The better one is the original from my Ford with 80,000 miles on it. Thanks for going over them,.
