Float Level Adjustment

On the 1920 there are dry and wet measurements to make. Dry with the carb bowl removed and inverted; wet with the carb installed and the economizer cover removed. Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download. Carb kits used to come with cardboard float gauges of the correct size and shape for whatever kind of carb is being built; no more, now they come with a useless strip-of-paper ruler.
