1973 Honda CB350F0 · Carb Rebuild Kits & Jets Buying guide

Separate rebuild contents from jet-size choices

Gaskets, metering parts and jets serve different needs during a rebuild. A complete kit can cover one carburetor’s service parts, while separate pilot sets let you select a known size for the whole bank.

Understand the rebuild package

One kit contains the float-bowl gasket, top gasket, O-rings, float needle and seat, main and pilot jets, needle, adjusting screw and spring. It services one carburetor. Compare the supplied jet sizes with the intended calibration before installing them, especially if earlier tuning work changed the bank.

Choose the pilot size deliberately

Honda’s parts information identifies size 35 as the standard slow jet and size 38 as an optional size for the CB350F. Both featured pilot sets supply four jets. Retain or change a size based on the verified carburetor and engine setup, not simply because pods or an exhaust are fitted.

Common questions

Does a rebuild kit cover the complete carburetor bank?

No. Each kit services one carburetor, so four kits are needed for the full bank. A pilot-jet pack is different: it supplies four jets of the selected size.

Should I choose size 35 or size 38 pilot jets?

Honda identifies 35 as standard and 38 as optional. Read the fitted jet markings and check the engine’s current intake, exhaust and tuning requirements before choosing either size.

Can I replace only a leaking float-bowl gasket?

A separate bowl gasket is linked for a focused repair. Inspect the bowl, sealing groove and fuel-control components first so the purchase addresses the source of the leak rather than just its location.
