1961 Honda CB77 · Fuel System Buying guide

Match the drain repair to the source of the leak

A drain screw and a float-control part address different faults. Inspect the affected area before making the order, and keep the fitted carburetor identity with your measurements if the assembly has been changed.

Parts to consider

Honda CB Stock Type Float Bowl Drain Screw Float Bowl Drain Screw with O-RingStock-type drain screw supplied with an O-ring and sold individually. Match it to the installed float bowl before ordering.View part

Identify the affected component first

Fuel at the carburetor does not by itself identify the drain screw as the failed part. Establish whether the drain hardware is damaged or whether the problem is elsewhere before buying. Keep the existing screw and bowl details available for comparison.

Account for replacement carburetors

The drain screw is listed for CB77 models from 1961 to 1968. On a motorcycle with replacement carburetors or float bowls, compare the screw thread, length and sealing arrangement against those fitted parts. Order by the installed assembly where it differs from the original application.

Buying questions

Does the drain screw come with its seal?

Yes. The drain screw is supplied with an O-ring and sold individually. Check the fitted bowl and old screw before ordering, especially if the carburetors or their bowls have been changed.

Should I buy a drain screw for a carburetor overflow?

First identify the source of the fuel escape. Overflow and leakage at a drain fitting do not necessarily call for the same part. Have the fault established before choosing between drain hardware and float-control components.

Should I order by the motorcycle year or the fitted carburetor?

Use both. Confirm the motorcycle identity, then check the carburetor and bowl fitted to it. A replacement carburetor can change the parts needed, and a model-year catalogue filter alone does not settle that choice.

Not sure which part you need?

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