Keep throttle trigger fully squeezed until
the engine runs smoothly.

the choke lever in the OFF CHOKE position;
then, pull the rope to clear the engine of ex-
cess fuel. This could require pulling the starter
handle many times depending on how badly
the unit is flooded.
If the unit still doesn't start, refer to TROU-
BLESHOOTING TABLE.
