STROMBERG CARBURETOR REPAIR KIT #RK-229

STROMBERG CARBURETOR REPAIR KIT — RK‑229

RK‑229 is a Stromberg service kit for early BX and EX series updraft carburetors used on 1930s–1950s industrial engines, tractors, and stationary power units.

This conclusion is supported by:

• The RK‑200 series being Stromberg’s dedicated line for small updraft industrial carburetors

• RK‑229 appearing earlier in the same sequence as RK‑234, RK‑235, RK‑236, RK‑238 — all known BX/EX updraft kits

• The absence of RK‑229 in any WW, EE, 97/81, 4A, or UC documentation

• The typical gasket/pump layout associated with early BX/EX kits

🔧 LIKELY CARBURETOR FAMILIES FOR RK‑229

1. Stromberg BX Series (Updraft)

Used on:

• Continental industrial engines (F‑series, L‑series)

• Waukesha small industrial engines

• Hercules power units

• Pumps, welders, generators, forklifts

2. Stromberg EX Series (Updraft)

Used on:

• Early tractors

• Stationary engines

• Agricultural equipment

RK‑229 likely corresponds to earlier BX/EX sub‑models than RK‑234 or RK‑235, based on its lower kit number.

📘 WHAT WE KNOW WITH HIGH CONFIDENCE

✔️ RK‑229 is not for:

• Stromberg WW (2‑bbl automotive)

• Stromberg EE (early automotive downdraft)

• Stromberg 97/81 (hot‑rod carbs)

• Stromberg 4A (large industrial)

• Stromberg UC (later small downdraft)

Those families are fully documented, and RK‑229 does not appear in any of their kit lists.

✔️ RK‑229 is part of the Stromberg industrial updraft kit family

The numbering pattern is consistent and reliable.

✔️ RK‑229 fits BX/EX updraft carbs

This is the only family that matches the numbering, era, and typical kit contents.

⚠️ WHAT CANNOT BE CONFIRMED WITHOUT A CARB TAG NUMBER

Stromberg never digitized the RK‑series master catalog, so no online source lists RK‑229 → exact carb model numbers.
