Is that true? I didn't realize there was a direct correlation.

Jaybird,
That is exactly my scenario. I have my family's `48 WD. It sat for 2 years and I completely restored it, down to the block. New wiring harness, spark plugs, wires from magneto to plugs. New Magneto, Just lined the gas tank, new fuel line, bowl, etc... The carburetor needs to be replaced, but it has a new kit in it and is completely cleaned as well.
It will run all day long, but just doesn't "sound" right to me. It sounds kind of like sputtering, but just rough. Not smooth at all. When it is idle, it sounds good to me. But under load / driving, it is rough sounding. |

Mine is similar. How do you adjust a magneto while running? Or can you? :)

You adjust a mag much the same as you would a distributor. Loosen both the top and bottom bolts that hold the mag to the governor housing and turn the mag.
As said above, it's possible (in a distributor) that the advance weights aren't moving freely. If the tractor was running good before, the only way for the timing to be off is if someone manually moved it.
I suspect your rough run is a dirty carb. If you use gas with ethanol, it tends to clean things to the point where there are a lot of snall particles moving around that can plug up some of the small orifices it the carb. Try removing the carb abd spraying carb lceaner through all the passages, then follow with compressed air. |

The correlation is the position of the crankshaft, when the points, actually open. W/o moving the distributor housing, if you close the gap, it will open the points sooner, advancing the the point, in which the coil fires. This is the way I time my vehicles, after setting the points. |

Thank you very much ac fleet! All I had to do was loosen the clamps(on the distributor) and make almost a quarter turn clockwise and now it runs like a top!

I don’t know how I can do that with a magneto? I can’t turn the magneto while it’s running. LOL it doesn’t work like that. How would I be able to adjust it?
