Need some guidance before I chase the wrong bunny down the wrong hole. Have the day off and need to use my time wisely. Perfect can wait, the goal for today is to get it running acceptably.

How likely is it that either of these is a contributor to my symptoms?

Vac advance- I did the "test" (thought maybe it was some kind of hazing ritual) but can't move the distributor. New vac advance needed. However, can a leaky vac advance contribute to running this poorly? I know there's no advance at idle, wondering more about the vac leak.

Heat riser- still stuck despite heating and penetrating oil. Verified on my parts motor that it is stuck in the "heat on" position. I could swap manifolds, but again, how likely is it to be major contributor?

Also don't have a lot of faith in my carb. Going to look at a couple things there.
