This is the position where the breaker points close.
What is Full Register Position?
100
The speed at which a sparkplug can dissipate generated heat into the cylinder head.
What is Heat Range?
100
This failure causes the contact points to take a blue/black color.

What are two types of breaker points?
200
The distance the firing end projects into the cylinder
What is reach?
200
This is a mechanical device that helps a magneto provide a hot spark for starting.
What is an impulse coupling?
200
This is how a booster coil sends its high tension pulse to the sparkplug.
What is a trailing finger?
300
The ignition switch is connected in series with the breaker points
What is the battery ignition system.
300
This is the point in time where the greatest magnetic stress occurs.
What is E-Gap
300
This causes a greasy black coating on the firing end of a sparkplug.
What is oil fouling?
300
The production of voltage caused by a moving magnetic field.
What is Magnetic Induction?
300
This is used to balance the RPM drop between two magneto ignition systems.
What is cross wiring?
400
This prevents condensation from causing flashover.
What is wax coated parts.
400
This is the position that the engine must be placed in for magneto to engine timing.
What is the full advanced position.
400
This is broken when a sparkplug is over-torqued.
What is a fired glass seal?
400
This is why the magneto P-lead is shielded.
What is R.F.I.
400
This is the sparkplug position that would be connected to the eighth magneto terminal on a 9 cylinder radial engine.
What is cylinder 6?
500
This device allows for the differing length of stroke in each cylinder of a radial engine.
What is a compensated cam.
500
rotating the 25 tooth section one tooth in the direction of rotation causes this change in timing.
What is 10.28 degrees advanced timing.
500
In a 6 cylinder engine with the firing order of 1-4-5-2-3-6, this is the position that the 2 bottom sparkplug would be moved to during a sparkplug rotation.
What is 3 top.
500
This is the result if a cracked distributor causes flashover.
What is miss-fire?
500
These brittle materials are used on fine wire ground electrodes
