Why Cobra RM46SPCE engine does not start?

  Mr. Isaiah HaleyAug 2, 2025
  If your Cobra Lawn Mower engine doesn't start, there could be several reasons. First, make sure the throttle choke is in the correct position. Check if the fuel tank is empty and fill it if necessary. A dirty air filter element can also prevent starting, so clean it. Ensure the spark plug is tightened to 25-30Nm and the spark plug wire is properly connected. The gap between the electrodes should be 0.7 to 0.8mm. If the spark plug is defective, replace it. If the carburetor is flooded with fuel, remove the air filter element and pull the starter rope until it clears. For a faulty ignition module, contact the service agent. If the engine doesn’t start with the key, charge the battery.

  If your Cobra Lawn Mower engine is hard to start or loses power, the issue might be due to dirt, water, or stale fuel in the tank; drain the fuel and clean the tank, then refill with fresh fuel. Another possibility is a plugged vent hole in the fuel tank cap, which you should clean or replace. Also, a dirty air filter element can cause these problems, so clean the air filter element.
