From Walt's tech tips

Here are the 1948 to 1956 metering rods for altitudes in Hudson Carter
Carburetors, WA-1 or WGD 2 Barrels. Sea level to 3,000 feet, standard
metering rods. 3,000 to 5,000 feet, 1 size lean. 5,000 to 8,000 feet, 2 sizes
lean. 8,000 feet and up, you must have 3 sizes lean. We will list year and
carburetor tag number. You know the altitude you are in, so make the right
choice. All rods start with 75, so I will just list lean by the last 3 numbers.
1948-49 six cylinder, tag #647S or 647SA, std-75-686 or 75-
-610-623-624-625. 1948-49 eight cylinders, tag #648S std-75-607-627-628-
629. 1950-51-52-53 and 54 Pacemaker and Wasp with 232 engines and a
single WA-1 Carter carburetor Tag #749S, std 75-704-712-713-714.
1950-51 and 52 eight cylinders, tag #773S-std-75724-744-745-746. This
carb can also be used on the 48 to 49 eight cylinder engines. 1950-51-52 and
53 Super Wasp and Hornets, tag #776S, std-75-754-732-741— -742.
1951-52 and 53 Hornets with Twin-H- Manifolds,
Carter WA-1 tag # 968s, std-75-834-861-862-863. 1954 Hornets with
Twin-H Manifolds, Carter WA-1 tag #2113S, std-75-955-974-975-976
1954 Hornets with 2 barrel Carter WGD, tag #2115s, std 75-732-980-
741-981. Here you can also use the carburetor number 776S. 1955 and 56
Hornet 308 engine 2-barrel WGD-tag #2252s, std 75-1169-1193-1194. 55
and 56 Hornets with 308 engines, with Twin-H manifolds use Carter WA-1
#2113S-same as 1954.

thanks for this info - are there other sources, i.e, Hudson, Carter? - also, which jet sizes go with which metering rod sizes?

- when i identified my metering rods, i could barely make out 75-352, even with an iphone magnifier app - i don't see those #'s listed above - maybe i have 75-862 based on similar looking #'s - i'll check again
