Troubleshooting
WARNING: Before performing any maintenance procedures, the engine should be stopped
and the spark plug wire disconnected.
Engine won't start manually
(Please refer to the engine manufacturer's owner's
manual for engine-specific procedures.)
Þ Are you priming? Push the primer bulb 3 to 5
times, releasing completely each time.
Þ Are you using fresh, clean gas? If it’s old,
change it. Use a fuel stabilizer if you keep gas
longer than two weeks or so.
Þ Does the 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.
Þ 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.
Þ Is the air filter clean? If it’s dirty, change it
following the procedure in the engine
manufacturer's owner's manual.
Þ Is the throttle cable attached to the engine and
moving freely?
Þ If your engine still won’t start, call 1(800)DR-
OWNER(376-9637) for advice and assistance.
Engine won't start using electric-start
(Please refer to the engine manufacturer's owner's
manual for engine-specific procedures.)

start above? If not, do so.
Þ Is your battery charged? Check it yourself or at
a gas station. If it’s low, charge it with a 12-volt,
1.5 to 2 amp trickle charger. If you don’t use your
DR

may need to be periodically charged. See the
