A 2006 Takeuchi TB125 starting, running for 10 seconds, and then cutting out with the water light flashing could indicate water contamination in the fuel system. Possible causes include:
- Water in the fuel filter or fuel system: Drain the water separator and replace the fuel filter if necessary. - Clogged fuel system: Air or debris in the fuel system can cause engine issues. Bleed the air from the fuel system. - Faulty water sensor: If the sensor is malfunctioning, it may incorrectly trigger the warning light and shut down the engine.
Check and drain the fuel system, replace filters if needed, and inspect the water sensor. If the issue persists, consult a Takeuchi service outlet.

Takeuchi tb125 2006reg starts runs then cuts out after 10seconds ,water light flashes turn off ignition and starts running again every time
A 2006 Takeuchi TB125 starting, running for 10 seconds, and then cutting out with the water light flashing could indicate water contamination in the fuel system. Possible causes include:
- Water in the fuel filter or fuel system: Drain the water separator and replace the fuel filter if necessary.
- Clogged fuel system: Air or debris in the fuel system can cause engine issues. Bleed the air from the fuel system.
- Faulty water sensor: If the sensor is malfunctioning, it may incorrectly trigger the warning light and shut down the engine.
Check and drain the fuel system, replace filters if needed, and inspect the water sensor. If the issue persists, consult a Takeuchi service outlet.
