Most likely, your carburetor is like the one at the link above. Here is the 1954 governor - it looks like the earlier one. The operation of that governor is described in those shop manuals. I do not see a mention of a speed-sensing device in the distributor, but I did not study the Shop Manuals very carefully. It looks to me like the adjustments are made in the governor assembly. The 47-55 GM governors that I have taken off of trucks up to 2-tons are as shown in those Shop Manuals (270 amd 261 engines). Are you missing the adjusting screw/cap and/or associated parts? Do you have the carburetor that came with the engine and governor? | | |
