Hi All,

I’m trying to check these points to see if they’re correct for my 22nd 288 with the Autolite 4502b distributor. I can’t find references to check the PPP numbers. These came with a load of spare parts, but there was also a delco distributor thrown in there.

Having a hell of a time figuring out the car. Idles fine but off idle it’s really rough to the point of unrunnable. Under load forget it. Doesn’t seem to be fuel delivery, I’m sorting through points/distributor now suspecting that. Started somewhat intermittently while driving, almost felt like a hard short, then over a day or two it got bad.

Thank you!

Maybe your coil?

Thanks, I’ll look at testing the coil, it’s pretty new but I have heard that the new Napa ones can go bad quick. It also came to me dented and in a box that was opened about 50 times previously so maybe it wasn’t the greatest to begin with. I’m mainly concerned about the vacuum advance or the weights, both of which I know minimally what to do if they’re bad but it sure seems like it goes off-time with throttle and certainly with load.

I put a new NAPA coil on my car and it only lasted a year. The oil leaked out and my car was running terrible. Replaced the coil with an epoxy filled one and all was well again.

If the diaphragm on your vacuum advance isn't leaking it should be okay. Not sure the weights often fail. I think if either of these were your issue they wouldn't be intermittent.
