★ This gauge is essential tooling for any Carter WO carburettor overhaul. Without correct adjustment of the metering rod, the carburettor will not function optimally.
Application
Used for adjustment of Carter WO carburettors as fitted to vehicles with L-134 engine. The metering rod must be adjusted with closed throttle — the adjustment pin must just fit in the gauge notch according to TM specifications. Later manuals (TM 9-1826A) specify max. 005" clearance between pin and shoulder of the gauge.
Installation notes
Completely unscrew the throttle adjustment screw and fully close the throttle. Place the T109-26 gauge under the metering rod adjustment pin. Loosen the lock nut and adjust the pin until it fits in the gauge notch (or according to later spec: a slight clearance of max. 005"). Tighten the nut securely. Remove the gauge and fit the metering rod with washer and spring. Always test operation: at idle a small clearance must be visible between the metering rod eye and the adjustment pin.
Compatibility
Exclusively for Carter WO (Model W-O) carburettors, such as Carter 539S and 636S versions. Not suitable for other carburettor types such as Zenith, Solex or later Carter YF models. Note: the adjustment procedure changed between 1942 and 1944 — early TM 10-1513 specified the pin "seated in notch", later TM 9-1826A specified "less than 0.005 inch clearance". Both methods have been used, engine response is decisive for final adjustment.
Historical context
The Carter T109-26 metering rod gauge was supplied by Carter Carburetor Company as standard adjustment gauge with Carter WO carburettors from WWII. The Army stock number was 41-G-196-50. Correct adjustment of the metering rod is critical for the economizer operation of the Carter WO — a carburettor design applied during WWII on millions of Willys and Ford military vehicles.
