Engine smokes.
Check the oil level and adjust as needed.

You may be using the wrong oil - too light for the temperature. Refer to your Engine
Owner’s Manual for detailed information.

Check the height of cut settings. Raise the height of cut if the grass is high.
Allow the engine to fully warm up if it is cold. The Auto Choke feature requires a cold engine
to heat to operating temperature prior to achieving full operating RPM.
Check the bottom of the mower housing. Clean the blade housing of grass and other debris.
Check for debris (hay seed, etc.) clogging the Air Filter Intake and clean out as required.
The Engine’s Blower Housing, Throttle Linkage, and Cooling Fins should be free of debris.
Clean them following the instructions in the Engine Owner’s Manual.
Check that the Air Filter is clean. If it is dirty, change it following the procedure in the
Engine Owner’s Manual.
Remove the Spark Plug wire and dry the connection with a rag.
The Spark Plug may be dirty or cracked, change it. If it’s oily, leave it out, hold a rag over
the Spark Plug hole and pull the Recoil Cord several times to blow out any oil in the
Cylinder, then wipe off the Spark Plug and reinsert it.
You should be using fresh, clean, unleaded gas. If it is old, change it. Use a fuel stabilizer
if you keep gas longer than one month.
Check that the Engine has the right amount of clean oil. If it is dirty, change it following the
procedure in Chapter4.
If your Engine still lacks power, visit our web site at www.DRPower.com or call 1-800-DR-
OWNER (376-9637) for assistance.
