The engine lacks
power or is not
running smoothly.
(Please refer to the
Engine Owner’s
Manual for engine-
specific procedures.)
⇒ Check the Throttle Lever travel and adjustment. Is the Throttle Lever
in the Run position?
⇒ Is the Choke lever pushed all the way over to the RUN position? See
Chapter 4.
⇒ Is the air filter clean? If it’s dirty, change it following the procedure in
the Engine Owner’s Manual.
⇒ Is the spark plug clean? If it is fouled or cracked, change it. If it is oily,
leave it out, hold a rag over the spark plug hole and engage the electric
starter for a few seconds to blow out any oil in the cylinder, then wipe
off the spark 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 two weeks or so.
⇒ Does your engine have the right amount of clean oil? If it’s dirty,
change it following the procedure in Chapter 5.
⇒ If your engine still lacks power, contact us at www.DRpower.com or
call 1(800) DR-OWNER (376-9637) for assistance.
Engine smokes. ⇒ Check the oil level and adjust as needed.
⇒ You may be operating the machine on too great an incline. The
machine should be level.
⇒ 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 engine cooling fins and the carburetor housing if they’re
dirty.
⇒ If the engine still smokes, contact us at www.DRpower.com or call
1(800) DR-OWNER (376-9637) for assistance.
