You don't use a light, you use a propeller protractor. Remove the magneto and set it to #1 by rotating it with your finger over the #1 spark lead fitting. If you are not that brave, use a curved wire, after it fires on #1 rotate the mag backwards and rotate forward until it hits some resistance. Rotate the center portion of the protractor until it is aligned with the proper timing in degrees. With the timing pointer behind the prop set to #1 place the protractor against the prop and rotate the prop in the opposite direction of rotation until the bubble is level. Insert the magneto rotating is slightly to maintain tension on the impulse coupling, and put in the bolts to hold it on. Hook up the leads and you are done.

Answer 3

There is no timing light that works with an aircraft engine that I know of. The timing of the mag is done by removing the Mag from the engine and adjusting the timing screws on the inside of the mag. There is a really neat tool that you have to hook it up to in order to get the correct timing. Be aware of this......I am not a Mech. I am a pilot so I may have completely screwed this up but that is the way I remember it working from the times I have given my Mech a hand.

Answer 4

the positives of the timing lights go to metal connecting the points to the compacitor, if that don't work, anything connecting to the points. the ground to any ground,preferably the mag casing. the lights go on when the points begin to open, signifying the spark. How you time the mag depends on the depends on the manufacturer's dierctions. usually you have to do the internal timing first, then time the mag to the engine. but be patient cuz it does need some fine tweeking
