Troubleshooting & FAQ
How do I know if this carburetor will fit my engine?
First, check the "Engine & Model Compatibility" table on this page. This part is designed for specific Tohatsu (M25C3, M30A3, M30A4) and Nissan (NS25C2, NS25C3, NS30A3, NS30A4) models from 2002–2005. Always cross-reference your engine's model number and year before ordering.
Does this carburetor come pre-tuned?
The carburetor is set to a standard factory baseline tune that works for most applications out of the box. However, minor adjustments to the idle speed or air/fuel mixture may be necessary depending on your specific engine condition, altitude, and local climate.
What are the signs my old carburetor is failing?
Common symptoms of a faulty carburetor include difficulty starting, rough or unstable idling, stalling at low speeds, poor acceleration, hesitation, black smoke from the exhaust (running rich), or visible fuel leaks around the unit.
Can I use ethanol-blended fuel with this part?
This carburetor is designed for standard unleaded gasoline. It can tolerate common ethanol blends like E10, but prolonged use of fuels with higher ethanol content may degrade internal seals and components over time. For storage, we recommend using a fuel stabilizer.
What maintenance is required for the new carburetor?
To ensure long-term performance, always use clean, fresh fuel and a high-quality fuel filter. Periodically inspect fuel lines for cracks and ensure all connections are secure. If storing the engine for an extended period, it's best to run the carburetor dry or use a fuel stabilizer to prevent gumming.
