I am looking for a 400 cfm AFB on Ebay and need to know what to ask so I can find that 400 model.

Like wise I have a 1966 Corvair/140 and am trying the same thing you are doing by using a Carter AFB.
It has a Holley 390 now but I prefer the AFB. Have you installed the AFB on your Corvair by now and if so how is it working.

no no not grease i just oil them, the thick gasket gets the grease but its a very very tiny amount

I do the same bro, I learned it from a carb rebuilder, he taught me it few years back and I try to pass any little bit I know on to others to help.
Greasing a Qjet pump now that's a new one to me?

the reason is when i hook them up ( mainly the 1406 ) if i need to take them apart to change jets and such the gaskets wont get stuck and tear, and i bought a ebay kit for the 1406 and it was piss poor quality, the gaskets tore everytime i removed them.....

Wd40 oils the gaskets up so they won't stick to the carb, as much as an untreated one does,
and it helps the Accelerator pump to seal a little better and move easier in it's bore.

|keitho64||I never heard of the WD40 on the gaskets or accelerator pump, that sounds like an excellent idea!|

I'm happy to help, Mikes will have it out to you quickly. your Welcome
A trick to help later with the carb, should it ever need a rebuild again, spray all the gaskets with WD40 before assembling it. and remember to spray WD40 in the pump bore before assembling it.

I ordered the kit from Mikes yesterday. I have the carb soaking in cleaner now until the kit comes in. I hope to have this done next weekend. I will post pictures when it is done.
Thanks for the tip on Mike's not only did they have the kit but I was able to get a manual and they have all the specifications / settings for the rebuild process.

You'll find the kit to rebuild it at Mikes carbs( carburetor-parts.com) or your local Napa will have it too.
Get yourself a lot of carb cleaner and clean every hole you can see, spray it with carb cleaner, then blow it out with air, or soak it in Chem -dry, but this stuff is nasty on the body but it'll clean the carb.
and she'll run good for you and will be dependable too.
I own 1 newer one and 3 older ones Afb's and they work. One thing check to make sure idle mixture screws aren't pitted if they are they do make them, Walker Products sells them.

OK I have confirmed the following numbers:
On the brass tag on carb top: 2632 and 4200S (you all were right)
On the side of the carb body: 0-1431 and then all the patent numbers.
On the carb base plate by the idle mixture screws it is J2 4200S
On the choke pull off arm: 180-137
Then is also has Carter AFB and Made in USA on carb body.
My plan is to put this on a Corvair until winter / early summer when I hope to move to a throttle body efi system.

Be careful with this one as it has longer metering rods, how I can tell is next to the air horn opening is a screw and a little cover and it has a raised up spot for the power piston.
It also has no secondary air valve like the other AFB's, so you may get a secondary bog, Jetting may need to be reworked a little.

Ok it's looks like a early model, most of them are 575cfm's, I can not see the numbers on the rightside flange, what are the numbers?
and what are the numbers on the tag?
because the flange is the model of carb and the tag is what revisions were made during the production process, this is what I was taught about them.
It looks like a 4200S carter AFB, it's around the 1960-62 yrs. because of the secondary venturis are still on the side of the bowl, not toward the rear.

|keitho64||And a couple more.|
