Core Policy


Guaranteed Carburetors includes a UPS return shipping label to send back your core from anywhere in the continental United States. Simply place your old carburetor (core) in the box, adhere the included return UPS shipping label, then give to any UPS driver or place in a UPS drop box.

We are liberal with our core return policy. Cores are the basis of our carburetor remanufacturing business. We require cores (your old carburetor) to maintain our carburetor inventories. Please return your core within three (3) weeks of receiving your remanufactured carburetor. If you think you may need more time to return your core, please list it in the comments at the end of the ordering process. The final page of the ordering process you will also be asked your vehicle info and carburetor identification number to verify you ordered the correct carburetor for your vehicle. If you are ordering a different carb or your core is damaged, disassembled or missing parts you will also have the opportunity to list this information in the comments. We will contact you if we need to clarify any info or concerns to ensure you receive the carburetor you need.

When payment is made using a credit or debit card on most vehicles, no core deposit is required. You are on the “honor system” to return your old carburetor (core) within 3 weeks from the date you receive your carburetor order. If we do not receive your core within this time period, you will be given a courtesy call or email for a reminder. After another 3 weeks (total 6 weeks from delivery), if we have not received your core you will be charged a core charge. If we do not receive payment from your credit or debit card your warranty will be void.

Note: We do not want money for your core unless you choose not to send it back. You can choose this option during the ordering process. We do want your old carburetor (core). This keeps your garage clean and ours stocked. We also recommend changing your inline fuel filter if your vehicle has one. The internal filter inside your carburetor is included with your carburetor purchase. We appreciate and value your business.
