1971 Honda CB100K1 Carb Floats & Drain Screws

Keep float replacement and drain-screw service as separate choices when ordering for a 1971 Honda CB100K1. The float comes with a pin, while the stock-type drain screw comes with an O-ring. Compare both against the carburetor currently fitted.

1971 Honda CB100K1 · Carb Floats & Drain Screws Buying guide

Match each small carb part to the job

Use the float reference and the old drain hardware to identify the parts needed. The included pin and O-ring help define the order without turning these individual components into an overhaul kit.

Parts to consider

Use the float reference alongside the fitted part

The featured float replaces reference 16013-286-014 and is supplied with its pin. Keep the old float available for comparison, particularly if the carburetor’s history is uncertain. The part reference helps identify the replacement; use the appropriate service information for settings and repair procedures.

Keep drain hardware separate from the float order

The drain screw is supplied with an O-ring and is sold individually, as is the float. Compare the old screw and the bowl it belongs to before ordering. If the bowl or its mating surfaces are damaged, establish the wider repair needs before buying only a screw.

Ordering questions

Can the float reference settle fitment after a carburetor swap?

Reference 16013-286-014 identifies the offered float with pin. Compare it with the installed carburetor’s identity and retained float; neither the motorcycle year nor a similar-looking bowl establishes the required float geometry.

Does the replacement drain screw come with its sealing ring?

Yes. The stock-type drain screw is supplied with an O-ring and is sold individually. Check existing kit contents before buying another ring for the same drain-screw repair.

Will a carb rebuild kit already include the float or drain screw?

The CB100K rebuild kit is described as servicing one carburetor, but its contents are not itemized. Check the actual package before buying additional parts; the separate float includes its pin and the separate drain screw includes an O-ring.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
