1981 Honda CB750K · Carb rebuild & jetting Buying guide

Compare sealing work with the fuller rebuild package

The smaller kit supplies a bowl gasket, needle and O-rings; the fuller kit adds listed jets and adjustment pieces. Separate jet sets have their own quantities, so check for duplication and match the installed carburetor.

Use the supplied contents to avoid duplicate purchases

A separate float needle is useful when that is the component needing replacement, but both featured carb kits already list a needle. The fuller package also lists jets and a mixture screw with spring. Check the repair list before adding separate pieces that a selected kit already supplies.

Keep jet names and package quantities distinct

The pilot sets are described as press-in jets, while main-jet assortments, main nozzles and needle jet holders have separate listings. Match the actual component and markings rather than selecting by a similar name. No available assortment establishes a setting or a performance gain for a changed intake or exhaust.

Questions before choosing parts

Why record the pilot-screw positions before a carburetor rebuild?

Honda’s disassembly instructions record the existing pilot-screw positions so they can be restored during assembly. Ask the technician to keep that baseline with the carburetor records; a replacement screw and spring do not establish the correct mixture setting.

Is the separately listed float needle a needle-and-seat kit?

The listing identifies a float needle only, under reference 16155-413-751. It does not claim to include a separate seat. Compare the fitted needle and the repair required before interpreting that individual part as a larger valve assembly.

Should I use a larger pilot jet after fitting custom filters?

Do not choose a size from that change alone. Match the installed carburetor and verify the required setting for its actual configuration. These listings offer several press-in sizes; the buying guide does not turn those choices into a universal jetting recommendation.
