1963 Honda CB77 · Fuel System Buying guide

Build the order around the installed carburetors

Start with the required components, then choose between an individual screw and the linked CB77 rebuild kit. Check any replacement carburetor or bowl separately before relying on the motorcycle application.

Drain screw to consider

Honda CB Stock Type Float Bowl Drain Screw Stock-type bowl drain screwStock-type float bowl drain screw with an O-ring, sold individually. The stated CB77 application covers 1961–68.View part

Related parts: CB77 carburetor rebuild kit

Avoid buying the same component twice

The drain screw is available separately, while the related CB77 rebuild kit has no itemized contents in its description. If you are planning an overhaul, ask what the kit contains before adding individual components. Do not assume it includes a drain screw, jets or a particular quantity of seals.

Keep replacement-carburetor details with the order

The screw and linked rebuild kit both cover the listed CB77 1961–68 application. A changed carburetor or bowl needs its own application check. Record its identification and any known replacement parts so the seller can assess the assembly you actually have, rather than only the motorcycle model.

Questions before ordering

Is the rebuild kit a better buy for a single missing drain screw?

The individual drain screw gives you one screw with its O-ring. For a larger repair, compare the kit’s confirmed contents with your repair list before choosing; the kit description does not establish that it includes this screw.

Does one drain-screw order cover both carburetors?

The screw is sold individually with an O-ring, not as a motorcycle-wide set. Count the screws you intend to replace and order that number; you can replace a single missing component without buying a pair.

What details matter if the carburetors have been changed?

Supply the fitted carburetor identification and any known bowl changes. Those details allow the screw or kit application to be checked against the replacement assembly, which may differ from the listed CB77 application.

Not sure which part you need?

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