1961 Honda CB72 Bowl Drain Screws

For a 1961 Honda CB72 bowl-drain repair, compare the removed screw with the replacement before ordering. The screw is supplied individually with an O-ring and covers CB72 1961–66. A replacement bowl still needs its own thread and sealing checks.

1961 Honda CB72 · Bowl Drain Screws Buying guide

Identify the bowl before choosing its parts

The featured drain screw includes an O-ring. Keep the screw and bowl identified together, because a carburetor body’s model marking may not identify a replacement bowl fitted during an earlier repair.

Parts to compare

Honda CB Stock Type Float Bowl Drain Screw Individual Bowl-Drain ScrewOne stock-type drain screw with an O-ring. Specified for CB72 1961–66; compare a changed bowl’s thread and sealing arrangement separately.View part

Compare the screw beyond its head shape

Keep the removed screw for comparison. The product description does not publish thread pitch or overall length, and a similar slotted head does not establish either dimension. Ask for those measurements if the original component is missing or the bowl has been changed.

Identify the bowl as well as the carburetor

A replacement bowl may change the screw and seal required even when the carburetor body is familiar. Record any bowl markings and the seal position before ordering. Use the relevant service information for refitting rather than applying another carburetor’s tightening specification.

Buying questions

Can I order the O-ring separately from this screw?

This product supplies the screw and O-ring together; its current variant offers no separate seal option. If only the seal is needed, confirm an appropriate separate part and its dimensions rather than assuming any similar O-ring is suitable.

What should I provide if the original screw is missing?

Provide the carburetor and bowl identification plus clear details of the drain opening and seal location. Ask the supplier for the replacement’s complete thread and length specifications before ordering; the description does not publish those measurements.

Does a replacement float bowl affect the screw choice?

It can. Confirm the replacement bowl’s required screw and sealing arrangement rather than relying only on the carburetor body or motorcycle year. Compare the documented thread, length and seal position before selecting the replacement.

Not sure which part you need?

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