Warranty & Returns

We are committed to ensuring that you are completely satisfied with your experience and have provided online technical support resources (above) to help you get the most out of your SmartCarb. See below for our warranty and return policies.

SmartCarb products and parts, including kit components are warranted to the original purchaser to be free of manufacturing defects in materials and workmanship for a period of six (6) months from the original shipping date. Any part that fails to conform to these conditions will be repaired or replaced at the discretion of SmartCarb Fuel Systems upon receipt of the defective part within the six (6) month warranty period. All warranties will be void under any of the following conditions:

  • Product was improperly installed or used in an application other than specified during purchase.
  • Product has been damaged, modified, or altered in any way.

During the warranty period, if you believe the product to have a manufacturing defect, please contact us for a Return Authorization Number. Please use appropriate packaging materials to adequately protect the product during shipping. Upon receipt of the returned product, we will inspect it and repair any manufacturing defects, replace the unit at no charge, or provide a refund less shipping costs.

If we determine that there are no manufacturing defects or that conditions are met for voiding the warranty (damage to the product, improper installation, or product modification), we will reset the product to factory settings and return it for the cost of shipping.

Metering Rod Exchange Policy:

SmartCarb Fuel Systems has an exchange policy in effect for metering rods. Any SmartCarb metering rod returned to us by the original purchaser free of damage will be refunded in full. Please contact us if you believe your application requires a different metering rod.

SmartCarb Fuel Systems recommends that SmartCarb owners perform basic maintenance on their carbs to keep them running at optimal performance. SmartCarbs should be cleaned seasonally and rebuilt with replacement service parts every year or two depending on use. Rebuild Kits containing all service parts are available for purchase here.

NOTE: Factory Refurbishing services for Cast model SmartCarbs has been discontinued. Rebuild Kits for Casts will remain available indefinitely.

We offer factory refurbishing to like-new condition for any billet SmartCarb whether purchased new or used from another source. Factory refurbishing includes a full tear-down, inspection, sonic cleaning, replacement of all service parts using a Rebuild Kit, reassembly, and baseline calibration specific to the application for which it will be used. The base fee for this service is $199 plus the return shipping cost. Any non-service parts needing to be replaced as determined by the inspection are extra. You will be notified of those costs prior to completing the work. SmartCarbs sent to us for factory refurbishing in excessively dirty or poor condition may be subject to an additional $30 cleaning fee or in extreme cases, refusal of service. Additionally, mail carriers may refuse to ship your package if the carb still has fuel in it so please drain the SmartCarb completely and give it a quick cleaning. Please contact us for a Return Authorization Number prior to sending the carb. SmartCarbs sent to us without a Return Authorization Number are subject to package refusal.

We want to ensure that you get the most out of your Smartcarb so please contact us with any questions you may have. We will ask for your carb’s serial number to best advise you.
