Compatibility Checks Before Ordering
- Compare the complete carburettor shape with the photographs
- Check both inlet/outlet throat diameters and rubber-manifold fit
- Compare throttle-cable mounting, linkage direction and return-spring arrangement
- Check the choke/starter-enricher arrangement
- Compare the electrical connector/heater wiring where fitted
- Compare fuel inlet, vacuum and breather hose positions
- Where possible, compare the original Honda carburettor number with the OE references above
Installation Notes
Before fitting a replacement carburettor, drain stale fuel and inspect the fuel tank, tap, lines and intake manifold. Contamination from rust, sediment or degraded fuel can immediately block jets or the float valve in a new carburettor. Final idle speed, mixture and cable free play may require adjustment after installation. Use the Honda workshop specification for the specific model and year.
What Is Included
One carburettor assembly with the accessory parts visible in the product photographs. Intake manifold, throttle cable, choke cable, airbox, fuel tank and vehicle wiring loom are not included unless pictured.
