struggle to accelerate

Hi John, sorry for your situation, I realise how frustrating it must be, if I was anywhere near I’d happily come take a look for you but I’m in South Wales... Regards, Iain.

Ballast resistors and their associated wiring do nothing but cause trouble in diagnosis. If you move to Alaska they might be useful

When was the last time the car ran normally?

leaving the ignition on in the wrong spot can burn the points. clean them

I have had new condensers be bad in the box, go back to the old one.

One more thought from left field.

Remove the distributor cap, twist the rotor, it should turn about 15 degrees and then spring back. If it doesn't you are not getting any advance with increasing RPM. You can also check this by connecting your timing light, checking timing at tickover, then increasing rpm and watching the timing mark moving towards more advance.

Regards,
Dan
