What kind of carb? The normal vendors will have rebuild kits for the original equipment Webers.

if you don't understand how the carb works, I'd highly suggest you either get a Weber or Fiat book so you can follow the rebuild procedure step by step. Any of the Fiat vendors will have carb kits or try Weber dists such as Pierce Manifolds.

Once you do get your rebuild kit, do not be surprised IF you find any of the below conditions:

1. parts are in your rebuild kit that do not fit your specific carb.
2. parts that you think should be replaced do not come in the rebuild kit.
3. parts identification list written in "pigeon" english. parts identification diagram too small to view by any human eye.

if you're not brave enough to proceed, get help. However, if you are comfortable with going with the flow, by all means proceed with the knowledge that it may take more than one attempt.

all of the above is from personal experience. your encounter may vary. it truly isn't that hard if you are paying attention to details, have a clean place to work, and have some fore knowledge. Download some exploded diagrams of your specific carb.

I hate to hijack, but I have a similar problem

I just finshed a complete engine and trans overhaull myself. I have the carb rebuild kit, but I'm reluctant to rebuid the carb. I can't be certain that It was adjusted properly before I took it off, but the car ran OK, no hesitation, shuttering, mis-firing. I have every fiat shop manual (3) plus the official fiat factory shop manual. All of them cover in detail how to rebuild the carb, and I feel confident that I can do it properly, but I am hesitant for two reasons:

1: the official factory shop manual says: The carb is a finely tuned precision instrument, and if there is nothing suspected to be wrong then dont fool with it. Even tiny scratches from cleaning can lead to failure of certain components.

2: Since the engine and carb would be rebuilt at the same time, there would be too many variables/adjustments to be made upon start up.

Should I leave the carb alone untill i get the engine properly timed and adjusted, then take the carb off and rebuild it ?

When rebuilding the engine I got into the "while you're there" mode, and
now I hate to put something on that I know I'll have to take off later.
However the carb is'nt the hardest thing to get to, and i want to complete my restoration the right way?

Has anyone had a carb component fail after they rebuilt the carb, related to how they cleaned or installed the part?

By the way its a 78 spider with the stock carb: Weber 32ADFA

thanks

can't imagine putting a 30 year old carb on a fully restored engine.

isn't that like putting a 60 year old heart into a 30 year old body?

Carb rebuilds serve their purpose, and do so well. but, if there is nothing wrong with yours, you could save $40

I already have the rebuild kit $27 from Vic Auto, I think I'm looking for a more technical response, or a specific order of operations: Ex: first tune comonent A, then B, then C.

thanks

Here's my technical response: I'd put the carb on the new engine if it was running okay to begin with, see how it runs, then rebuild and reinstall. That way, if the car doesn't run right, you know it's not an engine or ignition problem, but the carb rebuild.
Of course, this comes from someone who has to honk their horn to read the tach.

There are Weber rebuild services out there as well if you prefer. Some things are worth paying someone else to do. Cleaning septic tanks, rebuilding carbs, ect...

It should run you about $100-130 for a Carb shop to rebuild it
it might be worth the extra cost for you to drop it off and let
the experts take care of you .

follow Denise's suggestion.

You'll never know if you get your money's worth any other way.

Its difficult enough to get one running. Id say get her runnin first, with some clean, new gasoline. Overhaul it later! I have had to go and take them back apart to often because of improperly adjusting something, or some little doodad that got installed incorrectly! If you have customized the engine, the carb may need to be re-jetted? Santa is supposed to be bringin me a new Weber manual this year.
