1971 Honda SL350K1 · Carburetor Service Parts Buying guide

Order for the carburetor and the fault found

A needle-and-seat set, bowl O-ring and screw kit address different service needs. Check the existing carburetor and removed parts first, then use the stated package contents to avoid duplicating hardware or missing a sealing item.

Parts to consider

Honda CB Carburetor Screw Kit Carburetor screw kitHardware for two carburetors: drain screws with O-rings and 4 × 10, 4 × 8 and 5 × 12 body screws with lock washers.View part

Count the screw kit from its contents

The itemized kit contents are two drain screws with O-rings, eight 4 × 10 screws, eight 4 × 8 screws and two 5 × 12 screws. Body screws have lock washers. Compare these individual sizes and quantities with the fitted carburetors instead of relying on a broad screw-count summary.

Separate fuel control from bowl sealing

The linked float-valve set supplies a needle and seat, while the linked bowl gasket is an O-ring-type seal. Inspect the relevant parts and passages before choosing either. Use service information for the fitted carburetor when establishing adjustment and reassembly requirements after the repair.

Buying questions

Which screw sizes and seals are included?

The itemized contents specify two drain screws with O-rings, eight 4 × 10 screws, eight 4 × 8 screws and two 5 × 12 screws with body-screw lock washers. The kit is described for two carburetors.

Can the bowl gasket be chosen from the engine model alone?

Identify the carburetors actually fitted and compare the bowl’s sealing groove with the gasket outline. A carburetor swap can change the required seal even when the engine remains the same.

Does the needle-and-seat set also establish the correct jetting?

Its supplied parts are a float needle and seat. Jet selection and settings require information for the fitted carburetor and engine configuration; this set does not establish those choices.

Not sure which part you need?

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