I believe the mag is timed right, as it was running when I got it and I have not taken the mag off.
how do you check?

And don't even THINK of taking it apart without FIRST removing the output terminal--it unscrews just like a bolt.

Greg,you could try cleaning the copper collector ring inside the mag.Remove the wire,carefuly unscrew the brush holder, inside is the collector ring. I use rubbing alcahol on a Qtip.(you could probably use electrical contact cleaner also) Reach through the tapped hole the brush holder screws into,rotate the mag.Repeat until Qtip quits picking up crud.Also clean the brush and holder with alcahol.I have to clean mine every once in awhile.If you have a copy of the John Deere operating instructions it explains this.Hope this helps,Larry
