1971 Honda CB350K3 · Floats, Diaphragms & Covers Buying guide

Buy the component that matches the carburetor fault

A float repair, damaged diaphragm and missing top cover call for different parts. Record the installed carburetor details and the condition of each side before deciding whether you need one replacement or two.

Keep float and drain repairs distinct

The float is supplied with a pin and sold individually. The linked drain screw is also sold each and includes an O-ring. Check where fuel is escaping and inspect the parts involved so the order addresses the actual fault rather than replacing unrelated components.

Check what is being replaced at the top

The diaphragm item is replacement rubber, with 72 mm outside and 25 mm inside dimensions. The chrome top cover is a separate aftermarket part. Inspect the existing assembly before choosing either; a new cover alone does not replace the diaphragm beneath it.

Buying questions

Is the float pin included?

Yes. The replacement float comes with a pin and is sold individually. Inspect the other carburetor before deciding whether the repair needs one float assembly or two.

Does the diaphragm item include a complete slide assembly?

It is replacement diaphragm rubber, with 72 mm outside and 25 mm inside dimensions. Compare it with the installed assembly and confirm the repair method if the slide itself is damaged.

Can I buy a single chrome top cover?

Yes. The aftermarket chrome top cover is sold individually. Match the existing carburetor application and decide whether you need one replacement cover or two to give both carburetors the same finish.

Not sure which part you need?

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