    Why my Bolens BL160 engine will not start?
    • D
      Darryl GutierrezJul 26, 2025
      If your Bolens Trimmer engine won't start, it might be due to several reasons. The fuel tank could be empty, so refill it with properly mixed fuel. You may not have pressed the primer bulb enough; try pressing it 10 times or until fuel is visible. The engine could be flooded; in that case, move the choke lever to Position 3, squeeze the throttle control, and pull the starter rope until the engine starts. Old or improperly mixed fuel can also be the culprit, so drain the tank and add fresh fuel. Lastly, the spark plug might be fouled, requiring a replacement.

    How to fix Bolens BL160 cutting head that will not advance line?
    • N
      Nathan BrownAug 20, 2025
      If the cutting head on your Bolens Trimmer won't advance the line (for bump heads only), several issues could be at play. The cutting head might be bound with grass, so stop the engine and clean it. The cutting head could be out of line, requiring you to refill it with new line. The inner reel might be bound up or the line twisted, so rewind the line. Also, the cutting head might be dirty, necessitating cleaning of the inner reel and outer spool. The line could be welded, requiring you to open the cutting head and remove the welded section. Finally, not enough line might be extended; stop the unit, push the bump knob, and pull the line until 4 inches (102 mm) extends outside the cutting head.
