Troubleshooting & FAQ

How do I know if this kit fits my engine?

This kit is designed for Suzuki DF25/DF30 and Johnson-Evinrude 25/30 HP 4-stroke models produced between 2000 and 2007. The most critical step is to confirm your engine is not the Suzuki DF25 V-twin model, as this kit is not compatible. Always cross-reference your engine's original part number with those listed in our Part Number Matrix.

What are the signs my carburetor needs a rebuild?

Common symptoms include difficulty starting the engine, rough or unstable idling, stalling at low speeds, poor acceleration, hesitation, or black smoke from the exhaust. These issues often point to a dirty or worn carburetor with an incorrect fuel-to-air ratio.

How many kits are required for my engine?

This kit services a single carburetor. The engines listed in the compatibility chart have one carburetor, so one kit is sufficient. If your engine model has multiple carburetors, you would need one kit per carburetor for a complete overhaul.

Is this an OEM part?

This listing is for a high-quality aftermarket replacement part, not an OEM component. It is engineered to meet or exceed OEM specifications using comparable materials and is manufactured in an ISO 9002 certified facility with batch inspections to ensure quality and consistency.

How fast is shipping and what does it cost?

We ship worldwide quickly, with typical transit times of 5–15 days for most regions. Standard shipping is free. If available for your location, expedited shipping options and their costs will be presented at checkout.

What is the warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal use conditions. If you encounter an issue, please contact our support team with your order details. Returns are accepted within our standard return window for items that are unused and in their original packaging. Please see our policy page or contact us for instructions.
