Troubleshooting & FAQ

How do I know if my carburetor needs replacing?

Common signs of a faulty carburetor include difficulty starting the engine, rough or unstable idling, stalling at low speeds, poor acceleration, black smoke from the exhaust, or visible fuel leaks. If cleaning and adjustments do not resolve these symptoms, a replacement is recommended.

Is this carburetor pre-adjusted?

Yes, this unit comes factory-calibrated to baseline specifications for its intended engine models. However, fine-tuning of the idle speed or air/fuel mixture screw may be necessary to match your specific engine's condition, local altitude, and ambient temperature.

Will this fit my 4HP engine if it isn't listed?

While designed for the 4-5 HP range, guaranteed compatibility is limited to the specific engine models listed in the compatibility table. The most reliable way to confirm fitment is to match your original part number to one of the cross-references (e.g., 369-03200-0, 369-03200-1). Do not purchase if your part number does not match.

What maintenance is required after installation?

To ensure long-term performance, always use fresh, clean fuel and consider adding a fuel stabilizer, especially during off-season storage. Periodically inspect fuel lines for cracks and ensure the fuel filter (if equipped) is clean.
