318 Poly Vibration

Time to beat this dead horse some more.

I have started it to move it around over the winter, on a trickle charger, always fires right up and idles fine, for a while.

Pulled it out today, same as above. After a little bit kick the choke off, idles fine, a little more time, starts to idle down farther, too far to stay running at a light. Not yet warmed up totally.

Took it for an hour drive on back roads. Wanted to stall at stop signs. About a half hour in, would stay running at stop, but barely, and like crap.

The below vids are after the hour. That 4 blade fan sure makes quite the breeze.
Put it in drive then reverse.
The seatbelt buckle was chattering like crazy, which demonstrated the vibration I feel all the time.

Decided to Jurassic Park the vibration.
My dual quad 383 doesn't shake a bit.

If anyone can see/hear anything it would be appreciated.

I was thinking on getting a new carb, not sure what, or even why, just to eliminate it maybe as it's the only thing left not new I believe.

Going to try to drive it all week and see what happens.
