All, I noticed following my last cruise which was 200 miles or so, that my car's idle is shakey and rough, moreso when applying a small amount of accelerator. I can feel then engine vibrating until I rev to a higher rpm, the it is fine. Same while driving, it vibrates and acts as if it wants to stall unless I give it a lot of gas. Then it goes fine, althought I feel like with a bit less power.

Since I'm no mechanic, I can only speculate.
Accelerator pump?
Timing?

Not sure. Any input is appreciated.

Timing should always be checked as well as point dwell, but this sounds like a carb issue. Accel pump is not the root cause of the stated symptoms, I would go thru the carb if all else checks out first.

Check all your vacuum hoses too, especially around the brake booster and tank. Grab them and move them around some to see if they're leaking.
