Most of the kits I have bought from Larry were Walker.

In your situation, I can imagine the difficulty you must have after using parts from 7 different carbs - you might not know if the base plate came from a '69 383 B-body w/AC, and the top plate off a '70 C-body automatic.... the bores may line up but the metering might be different top vs bottom,...no?

And THAT's a difficult carb to find one kit for .. so maybe you ARE better off trying your parts bin and just trying until it works...

yes, well, I have an advantage, FOR SURE all carbs are post 72s, since no one TQ was used on earliers, beside some 340s

and I have keep matched the top and bottom plates, just checking for plastic bowl similarities, and linkages.

is not hard to guess what plastic body goes on which carb just checking for the emissions controls stuff blocking or not. after 8-10 years dealing with these I still can not say I know about this ( probably will never know about this ), but I have learnt something I think

NAPA sells them for less than $30 without floats but you get everything else. Of course they have floats too for them. It includes both 1 thick and 2 thin base gaskets.

#657-C I believe is the number.

yes thats the PN, I know thanks... that't the one being sold down here on mercadolibre.com ( same as ebay but local ), but B on box instead C... hygrade, dunno the diff on the last letter... maybe the size of the kit ? ( with or without floaters or whatever )

ok, got the O ring PN at the invoice.. is One of these:

QR-4011

or

QR-4108

more toward on the first one. I got both to check wich one was the best fit and as far I remember was the first one.

it was SAME outer and inner diameter... slightly and ALLMOST UNAPRECIABLE thickness size ( if some diff really ). TRUST ME they WORK!!!!

the second one ( if I'm right )was too thick and got broken when mounting... too much compression over the O ring

how many O rings do you want ?

believe or not THE TWO AT THE BOTTOM of pic are new and ORIGINALS!!! from rebuild kits. you can easily note the diff size of both EVEN ON THICKNESS, so as far you find an O ring that fits you won't have any problem to replace the old one... and gas/oil resistant of course.

the two above were selected to replacements, the one above them was obviouslly discarded ( is one of the PN I provided )

Forgett the caliper to compare them then LOL.

sorry the bad quality pic, is cell phone and at night.

I just need the brass floats. Who, where, how do I order, and how much?
Thanks.

here you go EL5
