Yep. Same exact carb on my Polara except screws are plugged. Does yours have the “cleaner air” sticker anywhere under the hood?
I’ll get some pictures of mine when I get home. I’m on the road for work for a couple of days.
My car also has a build date of April 10, 1968.
A little more background on this car:
It only has 38k miles and as far as I can tell it is the original carb. When I bought it it had sat since ‘93 (last year it was plated). It was originally sold in WV but it does have the “cleaner air” sticker on the inner fender. The only emissions part...
Thanks for the information. You definitely game me something to research on the idle jet circuit!
I just acquired the car this summer and got it running again this fall. I’ll try some ethanol free gas as well just for the heck of it too (albeit $5.50/gallon)…

I have a 1968 Polara with a 383 and a Carter BBD carb (tag #4578). I am having an issue with a lean surge (miss) at cruising speeds. It runs perfectly at idle and under load. I was wanting to adjust the idle adjust screws but this carb is one where the adjustments have been filled with lead...
