FROM YOUR SHOP TO OUR BENCH
How mail-in
service works.
You handle removal, installation and final tuning. We handle the removed carburetor.
Print, pack & ship
After checkout, complete and print your intake sheet and place it inside the box. Confirm our shipping address, drain and safely dry the carburetor, and pack securely. You arrange and pay inbound tracked shipping.
Receiving & inspection
We evaluate the carburetor's condition. Severe corrosion, broken castings, seized hardware, missing or damaged components and unusual configurations are discussed with you before additional work.
Bench service
We clean, inspect and reassemble using serviceable components and appropriate parts you supply. If parts are needed, we contact you before work continues.
Review any additional needs
Standard service is prepaid. We contact you for authorization if additional work is needed. Work may pause while you supply the correct replacement components; CarbBench does not source or purchase parts.
Return shipment
We return the serviced carburetor with CarbBench-arranged return shipping. Any outstanding authorized charges or required return-shipping payment must be settled before return. We reuse your original box whenever practical and provide tracking when available.
THE CARBBENCH BENCH SERVICE
Focused on
the carburetor.
We do not diagnose or repair the complete machine, remove or install carburetors on equipment, diagnose ignition, compression or intake problems, or perform vehicle-specific final tuning. Servicing the carburetor does not guarantee it will resolve the machine's underlying problem.
Pre-treat, clean & verifyComplete disassembly and chemical pre-treatment help break down stubborn gum, varnish, gasoline and ethanol-related deposits before ultrasonic cleaning, jet and passage verification, component inspection and compressed-air cleaning/drying.
Reassemble & documentReassembly with serviceable components, recording/restoring appropriate baseline or as-received settings, and a record of completed work.
You supply replacement componentsWe identify issues and contact you when parts are needed. You may provide the correct rebuild kit or components for installation. CarbBench does not source or purchase parts.
PREPARE FOR THE TRIP
Pack carefully.
Send it dry.
Do not ship a carburetor containing gasoline. Check your carrier's requirements for used fuel-system components before shipping; these packing tips do not replace those requirements.
- Drain all fuel. Collect fuel in an approved container. In a safe, well-ventilated area away from flames, sparks and heat, allow residual fuel to evaporate before packaging. Do not use heat to speed drying.
- Protect delicate parts. Cushion fragile fittings, linkages, floats, electrical components and any protruding parts so they cannot be bent or crushed.
- Bag only after it is dry. Place the dry carburetor in a sealed plastic bag. Separately secure and label any supplied components.
- Wrap and box securely. Use appropriate padding and a sturdy cardboard shipping box. Fill gaps so the carburetor cannot move. Do not rely on loose packing peanuts.
- Include your information sheet. Put your completed CarbBench intake sheet and any assigned reference/order information inside the package.
- Pay for CarbBench return shipping at checkout. Standard CarbBench return shipping is $35, selected and paid during checkout for standard orders. It applies to eligible shipments within the contiguous United States. Alaska, Hawaii, Puerto Rico, U.S. territories, international destinations and unusually large or heavy shipments require a shipping quote. We reuse your shipping box whenever practical.
- Use tracked shipping. Confirm CarbBench's shipping address first, then arrange and pay inbound shipping. Keep your tracking information.
