Why won't my Patriot LM 51 SP Lawn Mower engine start?
- J
  Jennifer HamiltonAug 5, 2025
  Several factors can prevent your Patriot Lawn Mower engine from starting. Ensure the choke lever is correctly positioned for the current conditions. Check if the fuel tank is empty and refill if necessary. A dirty air cleaner element, loose spark plug, disconnected spark plug wire, incorrect spark plug gap, defective spark plug, or a flooded engine can also be culprits. Tighten the spark plug to 25-30 Nm, install the spark plug wire, set the gap between the electrodes at 0.7 to 0.8 mm, or charge the battery. If the ignition module is faulty, it is recommended to contact an authorized service center.

Why is my Patriot LM 51 SP Lawn Mower engine difficult to start or losing power?

  If your Patriot Lawn Mower engine is hard to start or loses power, the issue might be contaminated fuel (dirt, water, or stale fuel). Drain the old fuel, clean the tank, and refill with fresh fuel. Also, check the fuel tank cap's vent hole for blockages and clean or replace the cap if needed. A dirty air cleaner element can also cause these symptoms; clean it to resolve the issue.

Why does my Patriot LM 51 SP engine operate erratically?

  Tanya FloresAug 22, 2025
  An erratic engine operation in your Patriot Lawn Mower can stem from a defective spark plug or an incorrect spark plug gap. If the spark plug is defective, you should install a new, correctly gapped plug. If the spark plug gap is incorrect, set the gap between the electrodes to 0.7 to 0.8 mm. A dirty air cleaner element can also cause this; clean it.
