1971 Honda CB350K3 · Carburetor Rebuild & Jets Buying guide

Match bowl shape, jet position and service quantity

A rebuild kit, screw assortment and individual jet solve different ordering needs. Check the carburetor body and bowl before choosing a kit, then select jets by position and size rather than by appearance alone.

Keep the two kit quantities straight

Each round-bowl rebuild kit services one carburetor. The separate screw kit covers two and contains two drain screws with O-rings, eight 4 × 10 screws, eight 4 × 8 screws and two 5 × 12 screws, with lock washers for those fastening screws.

Choose jet size for the installed setup

The linked #35 and #38 jets are slow or pilot jets; the linked #60 part is a press-fit primary main jet supplied with an O-ring. These are selectable sizes, not a prescribed setup. Compare existing jets and use appropriate tuning information for the actual carburetors.

Buying questions

Do I need two screw kits for two carburetors?

No. One screw kit supplies hardware for two carburetors. The rebuild kit is different: each services one compatible round-bowl carburetor, so a full pair needs two rebuild kits.

Which pilot size should I choose, #35 or #38?

Check the installed carburetor and existing jet style and size first. Select the size required by the motorcycle’s verified setup or tuning plan; neither available option should be chosen just because of the year tag.

Does the separate float needle and seat come as part of the rebuild kit?

A complete contents list is not specified for the rebuild kit. Confirm the required needle and seat before ordering duplicates; the separately offered Japanese-made needle-and-seat replacement has a stated CB350K 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.
