Not Ranked
First off... I want to say thank you to everyone on this post that gave ideas on what rabbit hole to go down. The car is back in order and I'm just getting around to post this update, but I'm not sure which of these fixed it. I tinkered with each area individually, but it wasn't until I tore everything apart at the same time... that any and all of these fixed it.
1) Just spraying wd-40 in the distributor seemed like it would temporarily work, but it was not until I took the springs out and removed the weights. You could not see the rust build up on the posts that the weights sit on or the rust in the little bushing that is on top of the weight.
- Sanded with super fine sand paper and put a very small amount of silicone spray.
2) I cleaned up the cap and rotor posts as well. Carbon build up on the posts, but not a lot.
3) Adjusted the auto choke and fast idle cam but did take it all apart to make sure that it was clean and freely moving.
4) The throttle shaft on the base plate had a small amount of wiggle to it. It seemed to be holding the throttle linkage up and wouldn't fully go back to starting position. This was a PITA to find, but glad I finally did. May eventually replace this part but for now it is working well. I sprayed some silicone on the main throttle shaft and at the next start up, the idle was very high then came back down. I was 100% sure I had a vac leak happening and would not of expected to look at this shaft potentially binding.
SO happy the RPM's don't climb on me anymore when driving! Back to having a fun and responsive throttle.
