1970 Honda CB350K2 · Carb Rebuild & Jetting Parts Buying guide

Match the carburetor before choosing its rebuild parts

A carburetor’s physical details matter more than a broad model tag. Keep left and right parts identified, compare the bowl and needle assembly, and record jet markings before selecting a rebuild package or individual metering parts.

Parts to consider

1970-73 Honda CB350K / CL350K Carb Rebuild Kit Round-bowl carb rebuild kitFor the listed 1970–73 CB350/CL350 round-bowl carburetors.

Separate a rebuild kit from a hardware refresh

The round-bowl kit is supplied for one carburetor. The screw kit covers two and lists two drain screws with O-rings, eight 4 × 10 screws, eight 4 × 8 screws and two 5 × 12 screws, with the specified lock washers.

Choose metering parts only after identification

Keep a record of the existing primary-main, secondary-main and slow jets before buying replacements. Honda’s parts catalog includes multiple jet choices, so a single size should not be assumed from the model year. Compare the needle-and-seat reference and the parts in your repair kit as well.

Common buying questions

How many round-bowl kits should I order?

Each kit services one matching carburetor. Order two for both carburetors, after confirming that the installed pair uses the round bowl configuration described for the kit.

Does the screw kit cover both carburetors?

Yes. It is specified for two carburetors and includes two drain screws with O-rings plus the listed cover screws and lock washers. Check the fitted hardware before assigning screws to their positions.

Is a listed jet size automatically the original K2 setting?

No. Confirm the exact carburetor and circuit using the applicable Honda information, then compare the removed jet’s style and markings. Multiple catalog choices and past modifications make a blanket size recommendation unreliable.

Not sure which part you need?

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