Not to be a smart ass but check them again.  I once chased a similar sounding problem on my Bluebird Special forever. Swapped out the coil early on with no change. Did a complete tune up and carburetor rebuild. Finally, tried a known good used coil. Problem fixed.

Good news/ bad news....

 

Good:  i got all tune up parts locally.. points,  condensor, rotor button, cap, and coil. 

 

Bad:  when i went to check the choke per beemon's recommendation:

A: choke heat tube is completely missing

B: secondaries in the carb base are frozen.  I tried to turn with pliers gently,  but they wouldn't break loose.

 

Ugh!  Carb rebuilds are expensive.  Is this something I could/  should attempt at home?  Would you believe I've never rebuilt more than a lawnmower carb... guess I've been lucky.

If your Century has a WCFB, I say rebuild yourself.  It is a fairly simple and forgiving carb.  I have some 54 Buick wcfb carb parts including the base.

Got this one... all the butterflies are free but it appears the accelerator pump is stuck.  Soaking it in warm soapy water now I don't want to pull the other one off the car since it's still running I'd rather rebuild one and then just swap

Matt, take your current carb (don't dismantle!) and make two baths for it - one in hot water, and one in ice water. If you read my thread I did on my WCFB rebuild, I had the same problem. Basically I'm assuming the WCFB came off of a grandpa car where he could have gotten by with a 2-barrel because he obviously never used the 4-barrel. Anyways, dunk the carb base in the hot and cold water a few times, holding it a few seconds in each bath, trying to turn the butterflies by hand. It should free up after about 4 or 5 transitions. As for the choke, that is definitely your driveability issue. Your secondaries not working will only give you part throttle but won't kill the engine. Your choke not opening after warming up will give you a really rich condition. If the heat stove is missing, go get yourself the Edelbrock electric choke for the interim. AutoZone/O'Reilly's should have them.

 

I should also note when using an electric choke, you have to file down the dog ear the spring rides on so it doesn't bind up. You don't have to file down much, and it's not a detrimental change. You'll also need a vacuum cap for where the heat pipe went, otherwise you'll have a vacuum leak there.

 

Alternatively, I supposed you could just swap bases, but my idea would save you from rebuilding for now.

Thanks.   And the choke is stuck open!  Lol....   I'll try your trick while i rebuild my spare.  Missing the heat pipe,  that vacuum leak might have been an issue too!

If the choke was stuck open and the heat pipe was missing, it was more than likely a vacuum leak issue. Something was obviously wrong in there!

So the bottoms of the two carters were slightly different.  I tried beemon's shock trick... no dice,  pulled the base,  heated with torch, disassembled,  cleaned, reassembled, running good!

How were the two bases different?

Different shaped butterflies,  and the vacuum port for the advance line was pointed the opposite direction

Was that off of the 55? I would have assumed the WCFB would be the same across years, but I guess they were technically still new and revolutionary for the time. How were the butterflies shaped differently? Just angle of attack in the base? Looking forward to seeing your car out and about on the streets!

Was of the 55. The vacuum secondaries were angled different,  but the vac port shape is what stopped me....  that's ok blue wrench fixed the 54

I noticed that the bores are smaller on the 54 compared to the 55 and 56...can't mix parts.

Drove downtown to dinner....  she stalled at every red light.   Got home and adjusted the idle mix screws and she seems to have smoothed out.

Seems like you have to get the engine nice and hot to properly adjust those idle mix screws.

Matt, your stance looks perfect! Looks like you won't need any springs any time soon!

Drove to the gym tonight, that minor adjustment made a big improvement!  When I came out of the gym this note was on my Buick.
