JohnD1956 Posted September 3, 2017 Share Posted September 3, 2017 Does the car have a dash pot. I think it's called a dash pot. maybe a dash pod. This is the small metal bellows with a pin and spring sticking out that comes into contact with the linkage at the carb. It is supposed to extend when you step on the gas. It's manual so no other lines or systems with it. And when you let off the gas pedal it is supposed to slow the return of the linkage to idle to prevent stalling. It is usually present on Automatic trans cars, not so much on stick shift cars. And if it returns to it's rest spot too soon the engine will stall. If you need pictures I can get some. 1 Link to comment Share on other sites More sharing options...

old-tank Posted September 3, 2017 Share Posted September 3, 2017 Think Electrical. The wire inside the distributor that goes to the points; Large cable on the starter shorting on the splash pan; any other loose wire or poor ground. . 1 Link to comment Share on other sites More sharing options...

MrEarl Posted September 3, 2017 Share Posted September 3, 2017 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. 1 Link to comment Share on other sites More sharing options...

MrEarl Posted September 3, 2017 Share Posted September 3, 2017 Btw, got a box for to mail the hood ornaments parts in, now just need a couple more weeks to get them packed then a couple more to get it out to the mailbox and you'll be set to finish that install. Can't wait to see that beauty mounted, it is nicer than the one I kept ya know? 1 Link to comment Share on other sites More sharing options...
NC-car-guy Posted September 3, 2017 Author Share Posted September 3, 2017 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. 1 Link to comment Share on other sites More sharing options...
old-tank Posted September 3, 2017 Share Posted September 3, 2017 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. 1 Link to comment Share on other sites More sharing options...
NC-car-guy Posted September 3, 2017 Author Share Posted September 3, 2017 (edited) Yes it is wcfb. I have a couple in my building, I'm gonna pull them out and degrease and see what i have.

NC-car-guy Posted September 3, 2017 Author Share Posted September 3, 2017 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 Link to comment Share on other sites More sharing options...
Beemon Posted September 3, 2017 Share Posted September 3, 2017 (edited) 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.

NC-car-guy Posted September 3, 2017 Author Share Posted September 3, 2017 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! 1 Link to comment Share on other sites More sharing options...

NC-car-guy Posted September 4, 2017 Author Share Posted September 4, 2017 (edited) 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! fill er' up Edited September 5, 2017 by wndsofchng06 (see edit history) 4 Link to comment Share on other sites More sharing options...

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! 1 Link to comment Share on other sites More sharing options...
NC-car-guy Posted September 4, 2017 Author Share Posted September 4, 2017 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 1 Link to comment Share on other sites More sharing options...

Beemon Posted September 9, 2017 Share Posted September 9, 2017 Glad you're having fun with the Buick! Feels great to finally be out there, doesn't it? I think people at shows generally gravitate to Buicks because they are so few compared to the amount of Fords and Chevies. 2 Link to comment Share on other sites More sharing options...
