Finally, after five years of slow-mo work, my truck was running and idling this afternoon.
Am I correct in thinking surging above idle speed is the govenor? I adjust it to the book specs when I rebuilt the carb but I suspect that the baffle plate is closing prematurely when I press on the pedal. It also stumbles, which must be the vacuum accel pump. I have heard that the plunger for the pump in these new carb kits is not the correct one, does anyone know what can be done to fix this?
Did I mention it RUNS??

Low flow fuel pump comes to mind, had a truck that did the same thing, checked everything else including carb float level and finally replaced the pump and problem solved. Something to think about.

Thanks for the suggestions, guys. The pump is drawing from a gas can currently, as the gas tank isn't ready to be reinstalled. I backed off the govenor setting and it smoothed out, even though I had set it according to the info in the manual when rebuiding the carb. Apparently it was trying to close the baffle at a fast idle. It's better now but I have to do some more adjusting to get it all working together.
There's still a lot to do but at least I am most of the way up this mountain of a project.
