SYMPTOM POSSIBLE CAUSE 
The engine won’t start. 
(Please refer to the 
engine owner’s manual 
for engine-specific 
procedures.) 
  Is the ignition switch in the “On” position? 
  Is the fuel shut-off valve on? 
  Are you using fresh, clean gas? If the gas is old, change it. Use a fuel stabilizer if you keep gas 
longer than 30 days. 
  Is the spark plug clean? If the spark plug is dirty or cracked, change it. If it’s oily, leave it out, 
hold a rag over the plug hole and pull the recoil cord several times to blow out any oil in the 
cylinder, then wipe off the plug and reinsert it. 
  If your engine still won’t start, contact us at www.DRpower.com for assistance. 
The engine lacks power 
or is not running 
smoothly. 
(Please refer to the 
engine owner’s manual 
for engine-specific 
procedures.) 
  Check that the Throttle Lever is in the “Run” position.  
  Is the air filter clean? If it’s dirty, change it following the procedure in the engine 
manufacturer’s owner’s manual. 
  Is the spark plug clean? If it’s fouled or cracked, change it. If it’s oily, leave it out, hold a rag 
over the plug hole and pull your recoil cord several times to blow out any oil in the cylinder, 
then wipe off the plug and reinsert it. 
  Are you using fresh, clean unleaded gas? If it’s old, change it. Use a fuel stabilizer if you keep 
gas longer than 30 days. 
  Does your engine have the right amount of clean oil? If it’s dirty, change it following the 
procedure in the engine manufacturer’s owner’s manual. 
  Check the oil level and adjust as needed.
