  Jessica GriffinAug 22, 2025
  If your Dolmar Trimmer engine stops quickly or its speed doesn't increase, start by warming up the engine adequately. Ensure the choke lever is set to “OPEN” once the engine is warmed up. Check and clean the fuel filter and air cleaner if they are clogged or contaminated. If these steps don't resolve the issue, the carburetor or drive system may be abnormal, requiring professional inspection and maintenance.
