A dirty carburetor causes the engine to stutter
A dirty carburetor is the number one cause of a stuttering lawnmower. Constant contact with earth, grass, leaves and twigs causes deposits in the engine so that it runs unevenly. By ordering a general cleaning of the carburetor, you can bring the fluctuating engine speeds back into line. How to proceed professionally step by step:
- Close the fuel tap or empty the tank
- Remove the carburetor, air filter and spark plug according to the instructions in the manual
- Replace worn seals with new ones
- Pour petrol into a vat and insert the removed carburetor
- Clean the air filter and spark plug

Let the carburetor soak in benzine for about 60 minutes. Rub the module dry with a cloth and install it. The clean air filter and the cleaned spark plug also take their place. Reconnect the plug and spark plug, fill the tank with petrol or open the petrol tap.
Readjust the carburettor on the petrol mower - brief instructions
After a thorough cleaning, a carburetor must be readjusted so that the lawnmower runs smoothly. When all components are back in their place, start the engine. Adjust the settings with a screwdriver while idling. Most commercial petrol mowers have two adjusting screws for regulating the engine speed and the amount of fuel. How to proceed:
- Screw in the adjusting screw for the speed a little
- In response, the engine speed increases
- Adjust the adjusting screw for the fuel until the engine runs smoothly
The brief increase in speed in the motor is fine-tuned in the last work step. To do this, unscrew the adjusting screw a little until you are completely satisfied with the lawnmower running.
Tips
Petrol lawn mowers have a weak point that can cause the engine to stutter, even on ultra-modern models. Always tilt your lawn mower to one side with the spark plug and air filter facing upwards. Otherwise, leaking oil and gasoline can clog important components.
