Rebuild Service Option:
We offer professional carburetor cleaning and rebuild services for this model. Pricing for the service varies depending on the type of carburetor, the number of carburetors in the rack, and any parts required such as rebuild kits, gaskets, O‑rings, jets, diaphragms, or other components needed to complete the job.
If you would like this carburetor rebuilt, we will create a separate Buy It Now listing specifically tailored to the exact carburetor you are purchasing. This ensures full transparency and full compliance with eBay policies.
Important: The purchase price of this carburetor and the cost of the rebuild service (including any required parts) must be paid separately through their individual eBay listings. We cannot combine these charges into a single invoice, and no off‑eBay payments will be accepted.
Handling Time Notice: Rebuild service requires additional time to complete. The standard handling time shown on this carburetor listing applies only to the carburetor purchase itself. If you choose the rebuild option, the rebuild‑service listing will display the correct extended handling time, and the rebuilt carburetor will ship once the service is completed.
Rebuild Eligibility Notice:
All carburetors must be in rebuildable condition to qualify for any cleaning or rebuild services offered. The buyer is responsible for reviewing all photos and descriptions carefully to verify the condition of the carburetor prior to purchase. All visible defects, cracks, missing parts, stripped threads, broken castings, corrosion, or other damage are shown as clearly and accurately as possible in the listing.
If the carburetor is found to be non‑rebuildable upon inspection, due to damage, corrosion, missing components, or any condition that prevents a proper rebuild, the rebuild service cannot be completed. In such cases, a portion of the service fee may be retained to cover the time spent on inspection, teardown, evaluation, and attempted service. This policy is necessary to protect against situations where the carburetor’s condition prevents a successful rebuild despite full disclosure in the listing.
By requesting the rebuild service, the buyer acknowledges that:
• They have reviewed the listing photos and description.
• They understand that the carburetor must be rebuildable to complete the service.
• They agree that a service‑charge deduction may apply if the carburetor is not rebuildable.
• They understand that rebuild service and parts costs are separate from the carburetor purchase.
Please message us if you would like the rebuild service added. Please see photos.
