My dad took off the mag to restore this tractor 15 years ago. He has started putting it back together and is not sure how to time the mag. It has marks on it and the bell housing has a peep hole with a cover. Is there marks on the flywheel you use to set the timing for the magneto.

This should work for you....

Magneto Timing for John Deere L & LA tractors :

1. Loosen the timing cover to see inside timing hole.
2. Remove the mag dist. cap.
3. Turn engine clockwise slowly until you hear the impulse trip. Stop.
4. Then turn slightly counter clockwise until you see the spark mark on flywheel in timing hole and it lines up with mark on center of timing hole.
5. At this place the points should just be beginning to open.
6. If not beginning to open loosen nuts on mag and rotate mag inward or outward until points just begin to open and then tighten nuts on mag.

If that doesn"t work to time with mag removed:

1. With timing hole open turn engine clockwise until spark mark is on the center of the timing hole.
2. Remove mag dist. cap.
3. Turn mag gear counter clockwise until dist. rotor is in 10 o"clock spot and then back clockwise until points just begin to open and dist. rotor is in 8:30 o"clock spot.
4. Hold mag in this position while installing on tractor and it may be necessary to turn some to align the gears and then tighten nuts.
5. If timed properly and when crankshaft is turned clockwise until the impulse trips the D.C. mark on flywheel should be at the lower edge of the timing hole when impulse occurs.
