* Manually choke the engine by blocking the carb intake venturi with your thumb or finger and
slowly pulling the starter rope a few times.
* Check that fuel is being sucked along the gas line up to the carb; continue slowly pulling the
starter rope until the gas line is clear of bubbles and you can feel fuel wetting your thumb or
finger.
* Remove your thumb or finger from the carb and open the throttle a bit less than half way.
* Slowly pull the starter rope one more time to check the engine is not flooded (see below).
* Smartly pull the starter rope in the usual way until the engine starts.
* Bring the throttle back to a steady idle. Do not allow the engine to overrev as this can cause
damage. You may find that you need to fine tune your throttle servo trim or the throttle linkage
so that the XP254M idles reliably but not too fast when the transmitter trigger is at its neutral
position. You may find it best to increase the servo trim setting for a slightly faster idle when the
engine is cold, then return the trim to its normal setting once the engine warms up.
Note: If too much fuel is sucked into the engine as you choke it, the engine will be flooded and
will not start. It may be harder to pull over on the starter as the excess fuel increase compression.
If this happens:
* Remove the spark plug and carefully wipe dry the electrode with a clean rag before setting the
plug safely aside.
* Hold a clean rag just above the plug hole and pull the starter rope smartly a few times to clear
the excess fuel (the rag stops the fuel spraying over you and the boat).
* Reinstall the spark plug and open the throttle a bit less than half way
* Slowly pull the starter rope to check the engine is no longer flooded. If it is, repeat the above 3
steps.
* Smartly pull the starter rope in the usual way until the engine starts.
* Bring the throttle back to a steady idle position.
