Re: Marvel carb
Hi 909,
FWIW: There was a vintage general rule for initial and general setting of vintage carburetor float heights shared by all of the old mechanics I knew when setting carburetor float heights, for all makes of vintage vehicles, which was to:
1. First separate the carburetor's bottom half from the top half and turn the carburetor's bottom half upside down; and,
2. Hold the bottom half up to eye level, and adjust the metal float tang until the metal seam in the float was parallel to the carburetor's bottom half's flat surface upon which the carburetor gasket rested.
3. This initial, general setting was found to be very close to how these carburetors were engineered and designed; i.e., the carburetor's float valve was in the closed position when the float floated upwards until the metal float was in the horizontal position, thus applying maximum upward lift to the float valve.
4. Even works today with unknown vintage carburetors on tractors, and all sorts of vintage engines with carburetors of different makes.
