Why NGP S421-C Lawn Mower engine will not start?
- C
  Charles ThompsonAug 2, 2025
  If your NGP Lawn Mower engine won't start, several factors could be the cause. You might be out of fuel, so refuel first. Alternatively, the fuel could be bad due to improper storage or refueling with poor quality petrol; in this case, drain the fuel tank and carburetor and refuel with fresh petrol. Other potential issues include a faulty, fouled, or improperly gapped spark plug, which may require replacement. If the spark plug is wet, dry and reinstall it. In some cases, the fuel filter may be clogged, or there may be a carburetor or ignition malfunction, or stuck valves, requiring component replacement or repair. Ensure to push the prime button.

  If your NGP Lawn Mower engine lacks power, consider these possible causes: the air cleaner elements might be clogged, so clean or replace them. Bad fuel could also be the culprit; if the engine was stored without treating or draining petrol, or refueled with bad petrol, drain the fuel tank and carburetor and refuel with fresh petrol. Also, the fuel filter might be clogged, or there could be a carburetor or ignition malfunction, or stuck valves, requiring you to replace or repair the faulty components as necessary.
