(quoted from post at 06:31:38 07/31/20) I pulled of the magneto shortly after i got this LUC cuz the engine was stuck. I now have the engine turning over good and ned to put the mag back on but don't know how to install it in the correct location. I have found the D/C mark and the PARK markings on the flywheel. Any Help would be appreciated.
I used google to search on the subject of your post "LUC timing the magneto" and found multiple hits. including the first one which has this text:
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.
