WCD Starter Adjustment
- If carburetor is installed on a Dynaflow car, make certain that throttle linkage and dash pot are correctly adjusted.
- If carburetor is removed from engine, connect a 6 volt battery and test lamp across switch terminal, so that the lamp will light when switch makes contact.
- Back off throttle stop screw, remove throttle connector rod (T), rotate fast idle cam (U) to slow idle position, if necessary and fully close the throttle valves.
- While holding throttle valves fully closed, place a scale against choke unloader arem (V) of throttle lever and make an index mark on carburetor body at the one inch division on scale.
- With ignition switch turned on (or test lamp connected) hold end of scale against unloader arm (V) and slowly open throttle until the drive pinion just engages flywheel ring gear (or test lamp lights).
- If switch is correctly timed, the scale will then read between 1 15/16 and 2 5/16 at mark on carburetor body (15/16? to 1 5/16? travel of arm).
- If necessary make switch adjustment by reducing or increasing the total thickness of the brass shims.
- If switch timing was found to be too early, reduce the total thickness of the shims. If timing was too late, increase total thickness of shims.

The image above illustrates adjusting the float using a Carter gauge. These gauges are not available but you can use a metal ruler. Just be sure both pontoons are the same. Make sure the pontoons are centered and when adjusting refrain from bending the pontoons themselves.
WCD Metering Rod Adjustment
Metering rod adjustment is important and must be made after completing the pump adjustment. No metering rod gauges are necessary. Procedure is as follows:
I . Back out throttle lever set screw to allow throttle valves to seat in bores of carburetor and loosen metering rod arm clamp screw (D).
2. With metering rods in place, press down on vacumeter link E until metering rods bottom in carburetor body casting F .
3. Holding rods in downward position and throttle valves seated, revolve metering rod arm (S) until finger on arm contacts lip (H) of vacumeter link. Hold
