Steve, you were not wrong on how the book describes the carburetor adjustment. The book however assumes the engine is sitting on a machine where constant RPM is desired. Here are the book descriptions showing that your comments were spot on for these engines in an industrial setting:
(Idle out 1 turn, Main out 1.5 turns in the book called pre-settings, and governor properly adjusted per chapter four) (Note that the clone carb idle settings will be far leaner, sometimes just a crack off of closed)
Start the engine and allow it to warm up to normal operating temperature (3 - 5 minutes). Set the speed control to the HIGH or FAST position. From the recommended preset position, turn the main mixture adjustment screw in (clockwise) slowly until the engine begins to run erratic (lean). Note the position of the screw. Now, turn the screw out (counterclockwise) until the engine begins to run erratic (rich). Turn the screw in (clockwise) midway between these two positions. This will be the best setting. (diag. 21, 22 & 23).
Set the speed control to the IDLE or SLOW position. Adjust the idle mixture screw following the same procedure used to adjust the main mixture adjustment screw.
