1974 Honda CB450K · Carb Floats & Other Carb Components Buying guide

Match the screw at the bowl’s actual drain connection

This purchase supplies the described drain screw with O-ring. Numerical thread dimensions and a complete seat drawing are absent. Compare the fitting and sealing location directly; the stock-type title cannot identify the connection on every carburetor or bowl substituted earlier.

Parts to consider

Honda CB Stock Type Float Bowl Drain Screw Bowl screw with its described sealing O-ringDrain screw is sold individually with an O-ring named in the description. Compare the bowl connection and old fitting before ordering. The listing does not provide thread measurements or a complete sealing-seat drawing for identifying an unfamiliar replacement bowl.View part

Separate this drain seal from unspecified kit O-rings

The drain description names an O-ring with the screw. General O-rings or a plug in a rebuild kit are not identified as this drain fitting or its matched seal. Confirm any overlapping kit coverage before assuming those internal contents replace the separate screw purchase.

Identify an unfamiliar bowl before relying on the replacement name

Where the original fitting is missing, establish the bowl identity and the thread and sealing specifications needed. Those details are not numerically given here. A changed bowl may require further confirmation before the listed motorcycle application can support this particular fitting choice.

Drain fitting identification and order quantity

What should I check if the old drain screw seals differently from the pictured fitting?

Compare the retained bowl and its sealing location with the screw described with an O-ring. Confirm the thread and seat measurements needed for that bowl. The written contents establish the offered seal, but no complete connection drawing resolves a different fitting arrangement.

How should I count replacements during a one-bowl repair?

Identify the screw needing renewal and verify its fit at that bowl. Each purchase is an individual drain screw with an O-ring described. Calculate quantity from the actual fittings being replaced, while evaluating other carburetor service parts from their own contents.

What can I confirm before adding this screw to a premium-kit order?

The premium kit names a plug and various O-rings without identifying this drain screw. Check the fitted bowl’s required parts and obtain any missing kit-coverage detail. A general plug description alone does not establish that the matched drain fitting is already supplied.
