What’s included and why it matters during installation?

Instead of sending only the carburetor, this Carbhub package supplies several common wear items so you can complete a more thorough service while the intake is apart. That reduces downtime and the need for immediate additional orders.

• 1x carburetor body — ready to mount
• 1x black throttle base cover plus 2 screws — secures throttle assembly
• Maintenance parts: air filter, spark plug, oil filter, fuel filter
• 1x plunger choke starter valve kit — aids cold-start reliability

How should I handle version differences or older shipments?

Carbhub notes the product was updated and sometimes earlier versions without the accessory kit may ship. If your delivery lacks the listed extras, contact the seller for resolution rather than discarding parts.

• Inspect package contents on arrival against the included list
• If accessories are missing, contact the seller for an updated shipment or support
• Keep photos and order information to speed any claims or replacement requests
