Really bogging down in 3rd gear

Thnx all. So i took a look at the dist again and turned over the engine. I think a small part of the issue is the points cam is wroe down. There are only small "humps" not sharp ridges left and i think that they arent even wore downevenly.
Can the points cam be removed and replaced?

They were never very sharply pointed when new. Look either directly above or below where the points rub on the cam. There should be virgin metal there where you can see if the lobes are worn. If you have a dwell meter, that will give you a more accurate reading than feeler gauges.

For something like this I always go back to basics. have you done a compression check yet? Could be a burned valve for instance.
