How to start a Stihl Lawn Mower when the engine won't start?

  Christopher EscobarAug 7, 2025
  If your Stihl Lawn Mower's engine won't start, several factors could be at play. Ensure the control bar for mowing is pressed as described in the instruction manual. Check if the fuel tank is empty and refuel if necessary. Also, verify that the spark plug socket is correctly attached and the ignition lead is properly fastened. The resistance at the blade might be too high, so try setting a higher cutting height or starting the engine in lower grass. Other potential issues include a blocked fuel line, inferior fuel, a dirty air filter, or a faulty spark plug, all of which may require attention from a STIHL specialist or spark plug replacement.

Why is my Stihl RM 248.2 T Lawn Mower engine power deteriorating?
- B
  Brooke SanchezAug 14, 2025
  If your Stihl Lawn Mower's engine power is decreasing, it could be due to several reasons. The cutting height might be set too low, or the rate of feed could be too high; adjust accordingly by raising the cutting height or mowing more slowly. Water or contamination in the fuel tank and carburetor can also cause this issue; in this case, empty the fuel tank and clean the fuel line and carburetor. Other potential causes include a dirty air filter or spark plug, low engine oil level, or dirty cooling ribs. Clean or replace the spark plug, add or change the engine oil as described in the engine instruction manual, and clean the lawn mower.
