1972 Honda CB350K4 Carburetor Floats, Diaphragms & Covers

Fuel-level and slide problems lead to different carburetor purchases. For a 1972 CB350K4, compare the float and pin, replacement diaphragm rubber and chrome top cover with the fitted parts. Inspect both carburetors without assuming every symptom requires replacing both complete assemblies.

1972 Honda CB350K4 · Carb Floats & Diaphragms Buying guide

Choose between float, diaphragm and cover repairs

These are individual carburetor components with different functions. Check the damaged location first, then use the supplied pin, rubber dimensions or cover reference to narrow the order.

Inspect the float assembly before ordering

The replacement float is supplied with a pin and is sold individually. Check the fitted float, its movement and the surrounding fuel-level components before selecting the repair. Use the service manual for adjustment rather than setting float height from the replacement’s appearance.

Keep the diaphragm repair separate from the top cover

The rubber diaphragm and chrome top cover are independent products. The diaphragm measures 72 mm outside and 25 mm inside and must retain the correct slide orientation. A cosmetic cover replacement does not establish the condition of the rubber underneath it.

Buying questions

Does the float include its hinge pin?

Yes. The float product is described as a float with pin, sold individually. Check the existing hinge and float arrangement before ordering for a carburetor that may have been changed.

Is the diaphragm a complete slide assembly?

The product is replacement diaphragm rubber, not a stated complete slide assembly. Compare its dimensions and the condition of the retained slide before choosing this repair.

What comes with the drain screw?

The linked stock-type drain screw includes an O-ring and is sold individually. Identify how many drain positions need repair rather than assuming a single item supplies both carburetors.

Not sure which part you need?

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