4. Measure the float height (A) from the float
chamber mating surface (B) by tilting the
carburetor so the float valve contact tab (C) just
touches the float valve rod (D). The float valve
spring (E) must not be compressed. Float height
should be 3-5 mm (0.12-0.20 in.).

level, and decreasing the float height raises the
fuel level.

rated to disassemble.
