Bring the starter into contact with the spinner nut or
spinner and depress the starter switch for one or two
seconds. Repeat if necessary. When the engine fires,
withdraw the starter immediately.

carburettor intake when applying the starter. Such an
action will cause an excess quantity of fuel to be
drawn into the cylinder and result in hydraulic lock
that may damage the engine.

Since a control line engine is started with the
throttle fully opened and reaches full rpm right
after starting, be sure to hold the model securely.
