    Carburetor Question

    What's up everyone. I was wonder what carburator are y'all running on the older caddys? I've got a 1953 deville with the stock 331. I can't seem to find a carb with the same size square bore as the stock carb I took out. Are y'all swapping intake manifolds as well? Any help would be appreciated. Thanks.

    Re: Cadburator Question

    1956 had the 365 motor with a carter carb. When you change carbs sometimes you need to change manifolds, make sure if you do you have hood clearance. Keeping it orig or going aftermarket is a matter of preference. If the car is all matching I would keep it original and get it rebuilt.









    Well......Obviously a 1953, see what you did brain. Scratch the first part, the later I stand by.

    I have to admit I was hesitant to rebuilding my carb by myself, but it wasn't that hard after all. I am happy I did it. I have to concur that rebuilding the carb is indeed the best option. You can find rebuild kits online like here <http://www.oreillyauto.com/site/c/se...&make=Cadillac>

    Re: Cadburator Question

    Well my problem is that my choke spring is worn out on the original carburator and can not seem to find one that will work. Every choke spring I find works the opposite direction that I need. I might just have to put manual choke on it but I would like to keep it all original.

    Talk to these guys - they have done several large Quadrajets for my boat engines. Nice work, not expensive. Long Island

    Re: Carburetor Question

    Generally, on old gals like the '53, keeping as much original as possible is preferred.
    But... sometimes an aftermarket carb may make a better driver.
    I'm usually leary of "Over-carbing" - where someone decides that if 390 CFM is good, 1500 must be better.

    Re: Carburetor Question

    There is no reason any number of places will not rebuild your carb, or you can do it yourself.

    Here is source for doing either - http://www.daytonaparts.com

    Is Your carbīs spring a spiral type? My other car has a Carter 4300S BBD with a thermal choke that burned up so I could adapt an electric choke for a Holley (works the same but the heat source is electric instead of exhaust heat). The cap was the same diameter but the spiral spring worked the opposite direction so I just turned it to the opposite position (left to right) and it worked right first time.

    Re: Carburetor Question

    I would think the choke spring would be able to be found/purchased. Have you tried Daytona Parts Co.?

    Also you state the spring "works the opposite direction." If you flip the spring over then in what direction does it work?
