1973 Honda CB350F0 Carb Hardware & Seals

Carburetor service often reveals damaged screws, worn drain-screw seals or missing small O-rings. For the 1973 CB350F0, compare a bank-wide hardware refresh with an individual replacement, and keep drain screws, mounting hardware and metering seals separate in your parts list.

1973 Honda CB350F0 · Carb Hardware & Seals Buying guide

Choose a hardware kit or one small repair part

The detailed screw kit covers several fastener sizes and includes four sealed drain screws. Separate drain screws and air-screw O-rings suit individual repairs, with each item’s package quantity determining how many to order.

Parts to consider

Use the detailed kit contents

The screw kit includes four drain screws with O-rings, sixteen M4 × 12 screws, eight M5 × 16 screws and two M6 × 14 screws, with lock washers. Lay out the old fasteners by position so you can compare the contents without assuming every screw uses the same length.

Avoid overlapping orders

A separate drain screw includes its O-ring and is sold individually. The small air-screw O-ring is also sold individually, but serves a different location. The linked forty-piece bolt-and-washer kit is another four-carburetor hardware option; compare its scope before ordering it alongside the detailed screw kit.

Common questions

Does the screw kit include float-bowl drain screws?

Yes. It contains four drain screws with O-rings, in addition to the specified mounting screws and lock washers. That can avoid an unnecessary separate order for all four drain screws.

Can I order one drain screw rather than a full set?

Yes. The separate stock-type drain screw is sold individually and includes its O-ring. Count the damaged or missing screws before choosing between individual replacements and the broader hardware kit.

Are the drain-screw and air-screw O-rings interchangeable?

They serve different carburetor locations. The drain screw comes with its own O-ring; the separate air-screw O-ring is listed at 2.8 × 1.2 mm. Match the seal to its location.
