16
Q

What does a low tension magneto system have that a high tension one does not.

A

The low tension has a high tension transformer at the spark plug

17
Q

What is a retarted spark

A

Ignition sparks for starting an engine, timed to occur later than the normal sparks

18
Q

What does the impulse coupling do

A

A spring loaded coupling between the magneto shaft and the drive gear inside the engine, used to produced a hot, late spark for starting the engine

19
Q

What does the impulse coupling use to lock

A

Can and flyweights and a spring to hold tension

20
Q

What are the two types of systems for auxiliary starting systems

A

Impulse coupling
Induction vibrator system

21
Q

What is the shower of sparks

A

The registered trade name of a popular type of induction vibrator starting system for a recip engine

22
Q

What is a system that was suppost to replace single magnetos

A

The double magneto

23
Q

What does a double magneto share

A

A magnet

24
Q

When timing a magneto what are the two types of timing

A

Internal timing
Engine to magneto timing

25
Q

What is internal timing

A

The adjustment of the breaker points of a magneto so they will begin to open at the time the magnet is in the e gap position

26
Q

What must the magneto be in to internally time it

A

E gap position

27
Q

What tools can be used to time the engine

A

Rotor holding tool
Timing plate
Magnito timing light
Timing marks
Time rite indicator

28
Q

What is carbon track

A

A trail of high carbon despostied by an arc across a high volatage component such as a distributor block

29
Q

What are the two types of high tension leads for a spark plug

A

Angled lead
Straight lead

30
Q

What are the two types of spark plugs

A

All-weather spark plugs

31
Q

What are the two sizes of spark plugs

A

5/8-24 and 3/4-20

32
Q

How can an ignition harness be tested for leaks

A

Ignition harness tester

33
Q

How are spark plugs moved

A

To the next plug in the firing order

34
Q

What is ice bridging

A

A spark plug failure that occurs when starting a recip engine in extremely cold weather. Water vapor for the combustion process condenses on the spark plug electrodes and freezes bridging the fire plug.

35
Q

What are the two types of electrodes

A

Fine wire and massive wire

36
Q

What are the two types of heat ranges

A

Cold spark plug
Hot spark plug
