CAUTION
Failure to troubleshoot a problem

WARNING
Draining fuel from the carburetor
can be hazardous.
Fuel can catch on fire if you do not
handle it properly.
When draining the carburetor,
always shut the engine off. Do not
smoke, and never drain or refuel
in an area where there are open
flames or sparks. Do not spill the
fuel or you may create a fire haz-
ard. Dispose of drained fuel prop-
erly.
