Remove the spark plug and reinstall it into
the ignition plug cap. With the engine pow

er system ON, move the sensor magnet past
the sensor quickly (by flipping prop or ma
-
nually moving the sensor past the magnet).
You should be able to either see the spark
or hear the clicking of the spark plug firing.
The engine RPM needs to exceed 180 RPM
before the ignition system will fire the spark
plug. Make sure to rapidly move the magnet
past the sensor when checking for proper
operation.
• Check fuel lines for damage or kinks. If any
of the lines are restricted, the fuel system
will likely not operate. Clean and intact
lines are essential for the system to operate
properly.
• Check for proper mechanical function by
turning the engine over.
• Check that the carburetor is correctly
installed and that all gaskets are intact and
undamaged.
• Check that the vent line is attached and free
from any bends or blockages.
