What to do if LawnMaster NPTBSP2609A Brush Cutter engine will not start but spark plug fires?
- F
  figueroadanAug 21, 2025
  If your LawnMaster Brush Cutter engine doesn't start but the spark plug fires, it could be due to several reasons. There might be excess fuel inside the spark plug, in which case you should remove the spark plug, clip the fuel tube to stop fuel from entering, and press the start button to clear the fuel from the cylinder. The fuel could be contaminated with water, requiring you to replace it. Other potential causes include worn cylinder and piston ring (replace them), a loose spark plug (tighten it), air leakage in the crankcase or cylinder (replace the gasket), lack of fuel (add fuel), no fuel in the primer bulb (prime the bulb), failure to engage the choke (engage the choke), or a blocked fuel tank valve (remove the blockage).

  If your LawnMaster Brush Cutter has no spark, the electrode of the spark plug might be wet, so dry it. There could be carbon deposit on the spark plug, so remove it. If the spark plug insulation is broken, replace the spark plug. If the spark plug gap is too big or small, adjust it to 0.026”±0.002” (0.65±0.05 mm). If the electrode of the spark plug is burnt out, replace the spark plug. If the high voltage line or stator of the ignition coil is broken or burnt out, replace them. Poor contact of the high voltage line and the jump ring should be amended. Lastly, a broken spark plug cap should be replaced.
