Sputter

OK, how did you determine this?

The reason I ask is some folks see gas when they open the throttle and think all is good. That is not necessarily the case.

When you crack the throttle with the car not running while looking in the carb, do you see an "instant" shot of gas? There should be absolutely no hesitation in seeing gas. If you move the throttle just a little before you see gas that's an issue.

Let us know.

yes, immiediate and a good shot, not a weak dribble.

You try running the vacuum advance of another source ? I moved mine and it solved the hesitation

what source did you use?

The leather around the accelerator pump plunger "likes" to shrivel-up because of all the damned ethanol that's in today's pump gas . Living in California , I see this firsthand quite frequently ! We have the worst gasoline here !

Rebuilding a Carter BBD is such a simple deal ; three main parts to the carb (Air Horn , Fuel Bowl and Throttle Body ) ; a finger-grasp of gaskets ; a couple of "Jesus Clips" ; Metering Rods (easily snapped or broken , so handle them like a Fabrege Egg !) and other basic items .
Residing in Arizona , you have access to real carb cleaners ; no need to "dip" the parts .

While you're at it , check the vacuum lines to the vapour canister (again , be careful as the phenolic plastic hose nipples are quite brittle after 40 years ! ) and replace its filtre , which is at the base .

Also , how's the EGR ? Is it clogged with carbon ?

what do you mean by real carb cleaners?

will triple check everything.

brand new egr, yes
