Thanks for the advice on calibrating the governor to a specific engine. I wonder if Dodge did this at the factory, or if it was not needed since the engine and governor were new.
This photo shows two different gasket styles and a spacer. On the left is a stack comprised of a metal plat sandwiched between two gaskets. According to the Mopar Parts List for Dodge Power Wagon 1947-1956, this is a Fuel Centralizer Plate and two Fuel Centralizer Plate Gaskets. This stack was found between the integral governor and the manifold flange. I removed this stack and other similar stacks from trucks with integral governors.
The gasket in the middle of the photo was removed from a truck with the later, sandwich style governor. This gasket was found between the throttle body of the carb and the governor. I have removed similar gaskets from other trucks with sandwich style governors.
I believe the spacer on the right in the photo is intended to be used when omitting the sandwich style governor. I believe the spacer would reduce heat that could cause carb icing and/or vapor lock.
The 1941-1947 Shop Manual for W Series Dodge Job-Rated Trucks states "When installing a governor on a truck not so equipped originally, the following parts, in addition to the governor itself, are required: Automatic choke rod (if so equipped); Vacuum line - Carburetor to governor; Long carburetor studs; Gaskets of a different type; Fuel pump to carburetor tube extension; Longer throttle rod; Longer air cleaner steady bracket. To install a governor, proceed as follows: 1. Remove the carburetor. 2. Remove studs in manifold flange and replace them with longer studs. 3. Install the governor in position so that the carburetor throttle valve and governor blade turn in opposite directions when closing. This is very important. 4. Install the governor using he special gasket between the carburetor and governor. This special gasket has 4 holes instead of 4 slots. If the special gasket is not used, the fuel mixture supplied by the carburetor will at times be too rich and neither the governor nor the carburetor will function properly resulting in overrunning of the governor or excessive fuel consumption." This confirms that the gasket with four holes is correct for installation between the carb and the sandwich style governors. I assume the gasket with four holes is also correct for installation of the spacer in the absence of the sandwich governor.
Can you confirm that the gasket with four slots is correct for trucks with the integral governor? Any other observations?
