The Engine won’t start.
(Please refer to the
Engine Owner’s Manual
for engine-specific
procedures.)
⇒ Check all of the items under the section called “Starting” on page 12.
⇒ There is a fuse in the wiring harness. Check the fuse and replace if needed.
⇒ Check the wire connections—especially the ground connection, the large green wire coming
from the Battery, where it connects to the Engine.
⇒ Check the wire connections to the Solenoid. Disconnect the green Battery ground wire first to
avoid sparks. Check to be sure that all of the connections are clean and tight. Reconnect the
Battery ground wire.
⇒ Check the ground connection on the Solenoid where it bolts to the Frame. Using a Wrench or
Socket, tighten the Bolts to ensure a good connection to the Frame.
⇒ The Battery may not be charged. Check the voltage yourself or at a Service Station. If it is low,
charge it with a 12-volt, 1 to 2 amp trickle Charger. If you do not use your machine for at least
45 minutes at a time, the Battery may need to be periodically charged. See the “Battery Care
“section on page 24.
⇒ If the Battery is charged and the Engine still will not start, visit our web site 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

⇒ Check the Throttle Lever travel and adjustment. Make sure the Throttle Lever is in the Run
position.
⇒ Check that the Air Filter is clean. If it is dirty, change it following the procedure in the Engine
Owner’s Manual.
⇒ The Spark Plug(s) may be dirty or cracked, change it. If it’s oily, leave it out, hold a rag over
the Plug Hole(s) and crank the Engine several times to blow out any oil in the Cylinder(s),
then wipe off the Plug(s) and reinsert it.
⇒ The gas may be old, change it. Use a fuel stabilizer if you keep gas longer than one month.
⇒ Check the Fuel Filter, it may be clogged. Replace if necessary.
⇒ Check to make sure that your Engine has the right amount of clean oil. If it is dirty, change it
following the procedure in the Engine Owner’s Manual.
⇒ If the Engine still lacks power, visit our web site at www.DRpower.com for assistance.
Engine smokes. ⇒ Check the oil level and adjust as needed.
⇒ You may be operating the machine on too great an incline. See “Slopes” on page 13.
⇒ Check the Air Filter and clean or replace if needed.
⇒ You may be using the wrong oil—too light for the temperature. Refer to your Engine Owner’s
Manual for detailed information.
⇒ Clean the Cooling Fins if they are dirty.
⇒ If the Engine still smokes, visit our web site at www.DRpower.com for assistance.
Before performing any maintenance procedure or inspection, stop the engine, wait five (5) minutes to allow all parts to cool.
