make sure the distributor hold down bolt is tight and that the distributor cannot easily be turned by hand and if it can, check the base ignition timing and also check that if there is a vacuum advance that the hose didn't fall off and that the vacuum advance is working, which can normally be checked by reving the engine slightly in neutral or park and pulling the vacuum hose off the distributor and putting it back on several times and listening for the rpm to go up and down, meaning that it is working.

Could the coil maybe b part of the problem as well
Classic Car Mechanic: Mike S., Classic Car Mechanic replied 1 year ago

Probably not, usually the coil either works or it don't but there is such a thing as a weak coil. If the timing hasn't moved, you could either have the coil tested, test it yourself with an ohmmeter or see if any shops nearby still have an engine oscilloscope that will test the coil output while the engine is running as well as test many more of the ignition.
