How to start a Dolmar Blower when the engine won't start?
- J
  Jose LewisJul 31, 2025
  If your Dolmar Blower's engine won't start, there are several potential causes and solutions: * Ensure you've primed the pump by pushing it 7 to 10 times. * Pull the starter rope strongly. * Check and feed fuel if it's lacking, clean a clogged fuel filter, or straighten a broken fuel tube. * If the fuel is deteriorated, replace it (recommended every month). * For excessive fuel suction, set the throttle lever to high speed and pull the starter handle. If it still fails, dry the spark plug electrode before reassembling. * Also, ensure the plug cap is securely attached, clean a contaminated spark plug, or adjust/replace the spark plug if there's an abnormality. * For abnormal carburetor, starter rope, or drive system it is recommended to request for inspection and maintenance.
