Carter Carb

i have a carter carburetor and i have no way to see what isze it is or anything like that, the thing boggs really really bad when i first give it gas, i can't get it to stay started when i put it in gear the only way i have been able to keep it going it to advance the timming so much that when i punch it i hear pinging, now from what i know tha pinging is from the pistons not being all the way up when it sparks so it pings for some reason, it is most likley bad for the engine but i will have to have it like that for a little while while i take it to get new parts and new tires, but i really need help to get it to work properly, so if anyone has had experience with this stuff before please help.

thank you

I'd guess that the primary float is out of adjustment and the accelerator pump is off. If I remember correctly there are some numbers stamped into the air horn or on the main body. If you can find them I have some old manuals and I'll try to find some settings for you.

well thank you

well the only numbers i found on it were on the body of it but here they are, i hope they work 9635SA 1543

i found this website http://cars.rasoenterprises.com/Carb-AFB_SetUp.htm

but i don't no what the heck he is talking about and i have no clue what he said would mean in the way of troubleshooting, and i have no idea what size rods he is talking about anyways

:CRY: :CRY:

The metering rods basically control the fuel flow through the jets at idle and come in more sizes than I can remember. They are mounted on a spring loaded arm above the jets. If you could post a picture if the carb it would help. I've messed with a few AFB's and it's my understanding that Thermo Quads aren't much different. Edelbrock bought out Carter a few years back and their carbs are updated AFB's.

is there anything specific i should take a picture of to help you


so i was told that these carter carbs are performance carbs and i was just wondering how performance they are, are they real performance or poor mans performance

No, just the carb. As far as your second statement, iin their day they were performance carbs. They didn't suffer the power valve problems that all early Holley's have, but IMHO they are harder to tune.

well i don't seem to be able to find the cord to hook my camera up to my computer with, my dad was talking to a freind of his at work and he says that he thinks the engine just needs to be broke in, so what yall think

I checked my old Motors and Chiltons and everything started with a 4, such as 40.., 41.., and so on.

Is there a way you can make a deal with one of your buddies to bolt on one of their "known-good" carbs so you can make sure it is a carb problem? If it won't stay running in gear, it could be a vacuum leak problem.

what everything started with a 4

Check these out www.carbcareusa.com http://www.cfiworld.com/everythingca...num/carter.htm http://aarc.epnet.com/application/90...Carburetor.htm

If all the links don't work do a search for Carter AFB.

well only the first site worked, but i need to find a site to see how big my carb is, everysite i go to never helps.

here are the pictures of the carb

i just posted pictures on my other thread and they worked just fine why is it working like this now.

Are there any numbers on the base of the carb underneath the ground wire?

Carter AFB Selection and Tuning Guidlines:

Carter AFB Tuning Manual:
http://www.federal-mogul.com/fmeconn...loads/1602.pdf

From Google: The 4760 is the carburetor to use if one requires a single 750 CFM 4-barrel AFB.

The 4762 is a "companion" unit with no choke for those wishing to put (2) 750 CFM 4-barrels as an in-line dual quad with progressive linkage (rear carb primary, front carb secondary). The 4762 has no choke.

Other units in the "competition series" AFB line are:

4758 500 CFM with manual choke
4759 625 CFM with manual choke
4761 500 CFM with no choke

For some reason, there was not a 625 no choke version.

Also from Google:
Be aware that these carburetors are calibrated for Chevrolet engines (low torque, high RPM). If you are placing them on a Buick, you will need to change the metering rods, and secondary air valves (possibly the idle tubes) for a really good setup. The metering rods have too great a difference from the high vacuum to the low vacuum step and will result in incorrect mixture at either the high vacuum or low vacuum (or both) conditions. The attack angle of the secondary air valve is too aggressive for a high torque engine, and will normally result in a momentary hesitation in the transission from primary to WOT. The idle tubes may not permit sufficient idle mixture for a good idle on the high torque engine

yes there are numbers under the wire, the numbers are the numbers that i already posted.

anyone think maybe it is the torque convertor, maybe i need a higher stall one.

A 9635 is a 625 CFM carb. These can be identified as Carter or Federal Mogul by looking at the suffix following the number. For these three numbers, the Carter will be an "S" while the Federal Mogul will be an "SA".

Soooooo yours is a SA so it was made by Federal Mogul. Your converter is not at fault. You need to either understand how to tune an AFB or find someone who knows.....a big pain.

Did this carb EVER run correctly on this engine?

well i only got the engine running for the first time (in my possesion) a few weekends ago, so all these problems are new to me.
