So I still have my hesitation, I checked the plugs to make sure all was connected, rechecked the firing order, thats all good. Put my trusty Champion spark plug pen on the wires when car was running to make sure wires were sending voltage to the plugs (love that antique pen) seperated the #5 & #7 wires to make sure they are not cross fireing.

Bucking, May be the carb. It is called a "Tip in stumble". Worn carb at a certain RPM. Gas at the top of the plate does not match the vaccume at bottom, or vice versa. Solved mine with a re-build.

Mark I was thinking carb, this car sat for so long it may have some gumming or crude comming loose now that it's getting some miles on it. I'm going to try and look at it today after work. I'll see if I can here the chirping while its in park. All U- Joints are original...........Maybe you need to come up a few day's early at the end of the month.....

Why waste a match?

A "chirping" noise, along with the bucking/hesitation, kinda sounds like an EGR issue, but it could very well be a vacuum leak...somewhere. Your mission, Mr. Phelps, should you decide to accept, is to find said vacuum leak, and repair. As always, if you, or any of your vacuum impossible crew should be found and fixed, we shall disavow any knowledge of your existence....

And...maybe check the carb baseplate/gasket...

A 3 speed overdrive?

Joel pretty sure I replaced that but i'll check it also....I forgot..... do you blow in the vavle to see if it's good .....or try to suck air out to see if it's good? ebo2011-07-12 05:28:00

Check for a bird's nest.

You're such a mechanic, Dave!

 I would be MORe than happy to help.

The tip in as Mark puts it is a setting in the carb that is done with those GM tools..I don't have....the stumble very well may be the egr valve not fully closed or maybe slightly stuck open..plate off the egr and see if it goes away..

Heh Rich, thanks..."plate off the EGR"?  Do you mean remove and block hole in valve cover?
