  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.

Why does my Dolmar Blower engine stop soon after starting, and the engine speed doesn't increase?

  Your Dolmar Blower might be stopping soon after starting, or the engine speed may not increase due to several reasons. First, ensure the engine has been sufficiently warmed up. If the engine is warm, check that the choke lever is set to “OPEN”. A clogged fuel filter or a contaminated air cleaner could also be the cause; in that case, clean them. Also, make sure the throttle wire is securely attached. If these steps don't resolve the issue, the carburetor or drive system may be abnormal, requiring professional inspection and maintenance.
