Carb. numbers on a '56 308

dougson

I saw in earlier posts information about the sequence of changes in Carter WA-1 carbs. on the twin-H motor. The earlier 968S units were replaced by 1953-54 with the 2114(?)s because of the addition of an idle improvement feature. However, in tearing down my '56 engine I noticed that both carbs. are 968S units, and they appear to be original, but maybe they're not. Anyway, is it possible that by the end of the 308's run, Nash was simply emptying the shelf or remaining carbs.?

Carburator exchanges are pretty common with Hudson engines. Over the years I have seen mis-matched pairs and wrong all together carbuator installations. Is the manifold you removed for a 56 engine? (integrated balance tube) If the manifold has an external balance tube it is the pre 55 varient and the carbs could be correct for the manifold? Lots to consider and usually none of it can be validated.:D

In revewing the Carter Carburetor data sheet for 1952-1956 Hornet engines using 968S and 2113S the only difference noted between the two are the metering rods. As follows:

Economy Step - (968S) .076"; (2113S) .075":

MIddle step tapers to (968S) .064"; (2113S) .068S:

Power Step - (968S) .056"; (2113) .059"

The only other difference is some of the gaskets - says "When servicing, use gasket assortment No. 198 (968S-2113S). Re-Carbureton kit No. 1723N (968S); No. 1776N (2113S)".

As long as they are paired you can use 968s or 2113s on 51 to 56 Hornets. Walt.

Walt, any advice for a guy that's putting a Twin H w/ newer manifold (integrated tube) and a pair of 2113S's on a basically stock '49 262 motor? Things like what float setting would you start out with? Thanks Doug

All floats on WA-1 carbs are set at 1/2 inch, with float cover turned over, then measure from rise on cover, it's a little 1/8 inch built up, to the top seam of the float. Don't try to press float, remove it and be very careful on how you bend the lip. It takes a lot of patience to set the float correctly. 2113s carbs will be to rich for your 262 engine with the 101.5 main jet and 75-955 metering rods. I would use a pair of 749s. If you need more info e-mail me, address in WTN. Walt.
