I am looking for an instruction sheet or advertising, have not found anything. It seems like it copies a lot of the characteristics of other carburetor brands like Schebler in particular. The one I bought seems to be New Old Stock - I am trying to decide if it warrants a cosmetic freshening or just try it and see how it works?
FYI the carb is installed backwards on the intake in the photo, and the photo is not of my carburetor or intake.
Found some data on The Old Motor - Thanks David G!
