1972 Honda CB500K Carb Floats, Seals & Hardware

A fuel leak or float problem on a 1972 CB500K can require a specific carburetor component rather than another full kit. Locate the affected joint first. Floats with pins, transfer-tube seals and drain screws have distinct contents; the preset float gauge is only a measuring tool.

1972 Honda CB500K · Carb Floats, Seals & Hardware Buying guide

Locate the problem before selecting a seal or float

The available choices separate an individual float, a twelve-piece fuel-seal kit and a drain screw with its O-ring. Check the component and how many carburetors need service. Keep a reusable gauge separate from the replacement items in the order.

Check whether the repair needs a screw or only a seal

The selected drain-screw source includes one screw and its O-ring, whereas the fuel-seal kit contains its specifically listed rubber seals. Inspect the screw and bowl seat before replacing hardware. Neither purchase is presented as a set of carb floats or a complete internal rebuild kit.

Measure with the right tool for the installed carburetors

The gauge is preset for the listed stock CB500K carburetors. It is not a universal tool for another carburetor set, and it contains no replacement fuel parts. Identify any swapped carburetors before using it, then follow the appropriate service method without inventing a float-height value.

Common questions

What comes with each replacement float, and how many are used?

Each float is supplied with its pin under Honda reference 16013-329-004. The compatible rack uses four floats. Confirm the carburetor application and count the positions needing replacement before ordering; the separately offered preset gauge is specified for stock carburetors.

Which joints are covered by the twelve-piece fuel-seal package?

It contains eight fuel-transfer connector O-rings and four bowl-drain seals for the compatible rack. Compare the leaking joint before selecting it. The separate drain screw references 16024-286-004 and includes its own O-ring, which can overlap a drain-seal requirement.

What must match when ordering a stock-type drain screw?

The selected screw references 16024-286-004 and includes one O-ring per individually supplied screw. One is used per carburetor, so four replace all rack positions. Compare the installed bowl and drain seat; new hardware cannot establish compatibility with a changed carburetor.
