I've never had a problem with my car. It's a 66' I-6. When I bought it, it came with a Holley Remanufactured Carb. I noticed it Idled rough and when I first hit the gas it shakes a lot. I thought nothing of it until recently. It has stalled more than 8 times in the last 2 days. I'll start the car, and it'll shake pretty badly, then it'll stall 20 seconds later or so. Think it's the carb? What to do?

Check your ignition system , points , rotor , cap , condensor , wires , coil. If it has been converted to pertronix , that could be your problem , they do fail.

I know it's electronic ignition, but I don't know if it's pertronix. Would the ignition make it stall like that or make it shake?

But it runs really smooth and nice when I'm giving it gas, would that be the timing or vibration damper still?

the only other reason i can think of for this would be bad motor mounts. those usually cause excessive vibration at low rpms, around 1000. but i am no expert now hopfully someone more experienced can give better advice

Sounds like a bad valve guide(s) to me. Very common on 200's.

Nevermind that, I figured out what it is, but how would I check that? Should I just take it somewhere and have them see if it's the valve guides?

Something you can check is for what will look like dirt or mud in your fuel bowl. This is caused by the pickup screen in your fuel tank rusting. Had it happen once before and the idle was terrible but would drive fine as long as you were in the gas.
