Lawn mower runs unevenly and smokes

A dirty carburetor brings the lawnmower out of sync

A common cause of engine problems on lawn mowers is a dirty carburetor. In view of the constant exposure to grass, earth, twigs and leaves, it is hardly surprising that deposits form here. If a gasoline mower stutters and smokes, subject the carburetor to a cleaning program. How to proceed properly:

• Close the fuel line or empty the fuel tank
• Remove the carburetor according to the manufacturer's instructions
• Remove all seals and replace them with new ones from a specialist dealer
• Fill a sufficiently large container with petroleum ether and place the carburetor in it
• Meanwhile, blow out each nozzle with compressed air or clean it with a fine wire
• Also clean the air filter and spark plug

Finally, take the carburetor out of the benzine and rub it dry with a rag. Again, refer to the instruction manual to help you install the carburetor. The installation of the carburetor is less complicated if you document every work step with a photo when removing it. This is especially helpful if the manual is difficult to understand or does not exist.

Readjust Carburetor - How To Do It Right

After cleaning, the carburetor will be new set. After you have installed the freshly cleaned carburetor, start the lawn mower. How to regulate the motor:

• Screw in the adjusting screw with the spring on the carburettor a little
• The engine speed increases
• Adjust the second adjusting screw for the amount of fuel until the engine runs smoothly

In the last step, unscrew the adjusting screw with the spring a little to reverse the short-term increase in the engine speed.
