+ | ** Tip for Inspecting Float Level - With Carb Installed ** | ||

+ | HD advised of a tip for adjusting the float level thru Tech Tip #36 dated September 1993. \\ | ||
+ | However, this only works if you have an overflow fitting on the bowl (carbs for 1200S models don't have this fitting). \\ | ||
+ | * Checking carburetor float level can be easily done without even removing the carburetor from the motorcycle. | ||
+ | * Simply attach a section of clear model airplane fuel line to the float bowl overflow fitting. | ||
+ | * A small diameter fuel line, which is compatible with gasoline, can be found in most hobby supply shops. | ||
+ | * Route the hose upward alongside the carburetor body. | ||
+ | * The motorcycle must be held level and be running to perform this test. | ||
+ | * Open the float bowl drain screw and fuel will rise in the hose to the same level as that in the bowl itself. | ||
+ | * In a carb with a properly adjusted float level the fuel level in this hose will be at the joint between the carb body and the float bowl face. | ||
