1980 Honda CB750C Carb Floats & Components

A float, accelerator-pump diaphragm and fuel-connector O-rings address different parts of the 1980 CB750C carburetor assembly. Identify the worn component before ordering a larger kit. Also compare the carbs actually installed, because replacement carburetor racks can change these applications.

1980 Honda CB750C · Carb Floats & Components Buying guide

Identify the float, pump or connector-tube repair

The float includes its pin, the accelerator-pump kit includes a diaphragm with rod and bellows rubber, and the connector O-ring pack contains twelve seals.

Parts to consider

Float service and pump service differ

The float replaces 16013-413-851 and includes its pin. The accelerator-pump kit replaces 16021-679-005 and supplies a diaphragm with rod and a bellows rubber. Keep those component references with the parts removed from the fitted carburetors.

Inter-carb seals have their own pack

The twelve O-rings are for fuel connector and accelerator tubes. Keep their locations distinct from bowl gaskets and drain-screw O-rings. Compare the old parts and the service instructions before disassembling the rack or selecting quantities.

Carb Floats & Components questions

Is the float needle supplied with the float?

The float package specifies its pin. Float needle 48-5011 is offered separately, while rebuild kit 48-1402 includes a float needle with sealing parts. Choose the needle separately when needed rather than assuming it comes with the float.

What if the original carburetor's float level is outside specification?

For the U.S./Canadian 1980 CB750C's VB42A carburetors, Honda directs replacement of the float when the correctly measured level is outside specification. Have the measurement confirmed using the model's procedure before choosing the replacement.

What should be checked before ordering the accelerator-pump kit?

Honda calls for checking the pump diaphragm for cracks or brittleness and making sure the pump rod is not bent. These checks help identify whether the diaphragm-and-rod assembly needs replacement before ordering a broader carburetor kit.
