1983 Honda CB650SC Nighthawk · Carb Floats & Small Parts Buying guide

Match small parts to their carburetor location

Float, drain-screw and shaft-seal work involve different areas of the carburetor. Compare the removed parts and the installed carburetor type before combining these items in a rebuild order.

Float and bowl-drain contents

The float product includes its pin. The stock-type drain screw includes an O-ring and is sold individually. These are distinct parts, so a float order does not automatically renew the drain seal or provide screws for every bowl.

Felt seals belong to shaft service

The twelve-piece felt set is described for throttle and choke shaft areas on compatible carburetors. Verify the fitted carburetor and planned work before buying it. Keep disassembly and reassembly tied to the appropriate service instructions rather than assuming the set suits every replacement carburetor.

Carb Floats & Small Parts questions

Does the float-and-pin package also replace the fuel shut-off parts?

It contains one float and its pivot pin, without the float-valve needle, seat or bowl gasket. Four floats are used across the rack, but inspect each carburetor and its valve components separately before deciding the order quantity.

What if the bowl drain still leaks after replacing its screw or O-ring?

Inspect the screw tip, O-ring groove, bowl seat and surrounding bowl for damage or debris. A new seal cannot repair a damaged mating surface. Avoid using extra tightening force to mask the leak; it can damage the screw or bowl.

How many felt shaft seals are in the set?

Twelve. The set is described for throttle and choke shaft service on the listed carburetor applications; confirm the carburetors actually fitted before ordering.
