Then, when intermittent firing starts, combustion assists in emitting the remaining oil. If the plug threads are too long, they extend into the combustion chamber and carbon adheres to the threads making it almost impossible to remove the plug. This opens the vibrator circuit and retard breaker points circuit. Magneto is also very good at reading people.
The engine continues to rotate until the piston of the cylinder to be fired reaches approximately a top dead center position. Timing the High-Tension Magneto to the Magneto When replacing magnetos on aircraft engines, two factors must be considered: 1. When the ignition switch is placed in the on position switch open, the interruption of primary current and the rapid collapse of the primary coil flux field is once again controlled or triggered by the opening of the breaker contact points. Base mounted magnetos are only used on very old or antique aircraft engines. As the magnet moves farther from the full register position, more lines of flux are short circuited through the pole shoe ends.
