Big Intake Tube is on GT5-SR / GT2-SM / GT2A and a Little Tube is on GT2B / & GT5.
Intake gaskets are different: 40mm hole spacing for the big one and 30mm on the little one.
The “Magneto” is the heart of the ignition system and is activated by permanent magnet
rotation. When a N./ S. magnetic flux field rotates past the magneto coil an induced voltage
impulse is sent to the CDI via blue / black wires so as to fire the spark plug at the right time.
Engine firing timing is not adjustable; Position of rotor is fixed to ensure correct timing.
If engine does not fire at start up check all bullet connections. Check if kill switch has an
unwanted ground. Make sure magneto has a good ground and not insulated by varnish.
