(SLICK IGNITION SYSTEM)
74-10-00 GENERAL
Conventional dual ignition is provide by two magnetos. The left magneto fires the six
(6)
upper spark plugs, while the right magneto fires the six
(6)
lower spark plugs.
The Slick
6214
Series Magnetos, manufactured by Slick Electro Incorporated,
530
Blackhawk
Park Avenue, Rockford, Illinois
61101,
are designed to provide ignition for six cylinder light
aircraft engines. The magnetos generate and distribute high tension current through high
tension leads to the spark plugs.
To obtain the retard spark necessary for starting, the magnetos employ an impulse coupling.
The purpose of the impulse coupling is to:
(1)
rotate the magnet between impulse trips faster
than engine cranking speed, thus generating a better spark for starting the engine;
(2)
automatically retard the spark during engine cranking, and
(3)
act as a drive coupling for the
magneto.
The following detailed explanation gives the meaning of the various numbers appearing in the
serial number.

74-10-01 MAGNETO INSTALWWON AND TIMING TO ENGINE
Before magnetos are installed on the engine, the rotation and internal magneto timing must be
correct. For rotation and interval timing procedure refer to the appropriate magneto manufac-
turer's instructions.
The magneto to engine timing check to be performed at every
100
hour and annual inspection.

Remove top spark plug from number one cylinder. Place thumb over spark plug hole and
rotate crankshaft in normal direction of rotation to ensure piston is on compression stroke.
Rotate crankshaft in normal direction until it is approximately
