All of the possibilities the fellas have suggested are plausible, and that makes it kinda fun, like playing "Clue". When it gets too drawn out, like a monopoly game stalemate (3 days!!) the fun dwindles.
I'm not one to react like a modern car pseudo-mechanic and suggest you just start replacing parts 'till you win, but a condenser is a part that is difficult to check under actual working voltage, engine heat, and frequency conditions. It is cheap and easy to swap out, so I'd start there. A meter test will tell the static capacitance and DC leakage, but that can be deceiving. If it is not the condenser, that's OK, it's always nice to have a known-good one in your trick bag of Model A tidbits. Go from there.
A coil is also difficult to test under heat and working conditions for internal insulation break-down and partial winding shorts. It is EXPENSIVE, so I'd run down everything else suggested in the replies first, unless you have a dizzy test machine or you're Rockefeller or have a bucket full of spare Model A coils, one of which may be good.
It was Professor Plum in the library with the candlestick. Do I win or am I out?
