Gary is correct. Call Moyer and/or join and post on the forums there. Those people rock! We could give you some basic suggestions, however, going on their forums might get you pointed towards the right answer faster.

Then really consider going to electronic ignition. Installation is not much harder than what you are doing every spring and it's one and done.

My Atomic 4 is 50 years old and still working. I'm glad to see the interest in Atomic 4 related subjects, even if the OP was 4 years ago and hasn't been back since.

Re: atomic 4 igniition points

A 'modern' retrofit/upgrade ignition system is your best bet for relatively trouble free operation of your A4:

Also do replace the coil, with one that is compatible with the (modern) electronic ignition system.

It will turn out to be one of the simple things (ignition on, resistor bad, most likely condensor aka capacitor bad) but while you are tracking that down, also consider getting an "ignition point file".
https://smile.amazon.com/s/ref=nb_sb...ion+point+file
This is just an inexpensive, thin, fine surfaced file that is designed to be held in between the ignition points and then used to polish down both sides at the same time for a uniform cleanly matched surface. You can often clean up burnt or worn points three or four times this way, so you don't need to buy new ones anywhere near as often.
You can also improvise the same tool by wrapping or gluing some extra fine (400-800) grit wet-or-dry sandpaper on a piece of metal or plastic shim stock.

Of course if you haven't done a major tuneup (including the condensor and ballast resistor and coil) in a couple of years, it might be most effective to simply replace them ALL at the same time, and move forward knowing you've got a solid foundation. They all eventually wear, mainly from heat, and the coil on the A4 is known to take heat damage more often than you'd expect.

Spark plug wires, btw, should also be tested with a multimeter, set on the ohm scale. Ballpark numbers regardless of length are that anything under 1000 ohms is "new", up to 5000 ohms is "good", 10,000 ohms is still ok, and anything higher than that? Is time to replace. You may find 10-20,000 ohms on what look like perfectly good wires, time to replace them if they are that high. No need to replace them until the resistance goes up, regardless of their age.

Re: atomic 4 igniition points

Do you have a ballast resister? If not, the points see full 12 all the time instead of just while cranking (which isn't really 12 because of voltage drop of starter but coil is designed for 8 .New electronics would be a good place to make it all better.

Replace the whole primitive mess with an electronic conversion kit.

Re: atomic 4 igniition points

Points burn out because of constant current flowing through them for to long with out the engine running . or you need to check all connections back to ground if the distributor mounting surfaces are not clean and dry they can cause high resistance that can burn out points make sure all grounds on the motor are also clean and dry. if the alternator spikes like say you disconnect the battery wile it is running you can burn out points usually this causes the diodes in the alternator to go out and you would need to replace the alternator but you could get lucky and the alternator still works. and last I will give you a scenario that I bet every one has done ones or twice. I see this time and time again on the Model A fords I work on for my Club. So you are working on the motor and the battery runs down you connect a charger to charge the battery wile you are working on it you leave the key on .

Do you have the Delco Distributor?
