Title: need help identifying carburetor
Post by: AndrewG on April 19, 2015, 09:46:20 AM
I need to identify the carb on my 1980 Pinto engine.  The base of the carb is stamped with the number 8355.
The left side of the carb, on the assembly near the choke index notch, has the following info.
Motorcraft
47R-635A
9J24

Can someone help me identify this carb. I would like to be able to work on it and get the correct rebuild kit for it.
Thanks

TAG is all you need to get a kit.

X2, the tag is what they will want to get a carb kit, the carb itself is a 5200 but the calibration on the tag tells what mods are on the carb, maybe 100 different ones.

Thanks.
I'm also looking for info on how to properly adjust the carb.
Can I use the adjustment settings for any 5200, or does the info on the tag on it's mods to the carb affect the adjustment settings?

Any 5200, leave the idle limiter caps off. Pay attention to the choke plate qualifying setting, both on the choke cap and the drill bit size used to set the choke plate if not fully closed. Screw the mixture screw in to a light dead stop and counting the turns while doing so and start there when cranking car back up again, or 1 to 1 1/2 turns if lost. Start idle speed screw with the throttle plates both barely exposing the transfer slots or hole maybe .020" and that means setting the back barrel too. Many leave that back closed and it warps you into opening the front too much to then be too high in slots and then too rich and car won't pull right off idle.

Thanks for the great advice!

Go to the post #5 pic and the secondary idle speed screw is plainly visible right under the 'Y' in the word 'university'.............. ...the small slot screw is staked but you adjust it if needed to make up for wear or just to get that secondary throttle plate in the correct position on its' slot or first hole. Some have a slot there, some a series of small holes, same thing, works the same way, like an accelerator pump for just off idle, they add rich as the throttle opens up away from idle otherwise the engine would balk at the sudden drop in vacuum (goes lean) when the throttle opens.

Thank ToniJ1960 for that link.......... .............. .
