I'm spitballing here... my truck has occasionally suffered loss of power and jerking.

I've changed fuel filters, the plugs and wires are new, I even drained the gas tank and inspected it. This was last fall, and I didn't experience the issue until the end of June. Well we have 100% humidity in Va right now and yesterday it was the worst I've seen the symptoms. She will stay running as long as I let way off the gas and the symptoms eventually resolve but I would like to get to the bottom of it.

The truck is desmogged. What I read in general is weak ignition coil, cracked distributor cap... any thoughts appreciated. New Weber carb. Truck runs fantastic aside from this intermittent issue.
 
I could never get my weber to not run rich... definately look at your ignition. Does it have OEM ignition, or HEI. How is you tank vented? Have you checked for vacuum leaks?
