1973 Honda CB750K · Carb Floats & Other Carb Components Buying guide

Match the component to the location being repaired

Choose seals by their location: connector tubes, bowl drains and air-screw needles use separate products. The float comes with its pin, while the drain screw includes an O-ring; check these contents before adding loose pieces.

Distinguish the seals in a carburetor service

The connector kit supplies eight fuel-connector tube O-rings and four bowl-drain seals. It is a defined set for those locations. Air-screw needle O-rings have a separate 2.8 × 1.2 mm specification and are sold individually.

Check the parts already included

The float includes a pin, and its application specifies four floats per bike. The replacement drain screw is sold individually with an O-ring. Compare those contents before ordering a separate pin or drain seal for the same repair.

Common questions

How many floats does the application call for?

The float application specifies four per bike and the replacement includes its pin. Order for the floats actually being renewed; the four-per-bike note does not describe a four-float package.

Does the connector kit cover the air-screw needle seals too?

Its stated contents are eight connector tube O-rings and four bowl-drain seals. The air-screw needle O-ring is a separate individually sold part, specified at 2.8 × 1.2 mm.

Do I need another O-ring with a new drain screw?

The stock-type replacement drain screw includes an O-ring and is sold individually. Check that included seal before adding a separate bowl-drain seal for the same screw.
