Troubleshooting
IGNITION SYSTEM CHECK
1. Remove the spark plug and reattach it to the spark plug lead.
2. While holding the spark plug firmly against the engine, push the start-
er button with the engine stop switch cap is installed on the remote en-
gine stop switch. If the ignition system is operating properly, a blue spark
should jump across the park plug gap. If there is no spark, take your
machine to your authorized dealer.
Do not check for a spark unless you are certain that you know how to do
it; you could get a high voltage electrical shock. When testing for a spark,
do not point the spark plug near the spark plug hole. There may some
fuel inside the cylinder which could be ignited. Due the possibility of
electrical shock, anyone with a heart condition or pacemaker should avoid
this check.
PROBLEM:
Engine stalls
1. Make sure there is enough fuel in the fuel tank.
2. Check to see that the spark plug is not fouled. Remove the plug and
decarbon or replace it, if necessary.
3, Make sure the fuel valve is clear. Also check the air vent hose connected
to the fuel tank cap is not clogged.
When draining the carburetor, always shut the engine off. Do not smoke,
never drain, or refuel in an area where there are open flames or sparks.
Be sure to use a suitable container to catch the fuel out and drain from the
carburetor. Do not allow the fuel to spill or you may create a fire hazard.
Keep fuel out of the reach of children and pets or they may be injured.
