thanks.
You could make one magnet stronger than the other. Usually they are anyways on most motors, but not enough to make a difference.
However you would almost need to remove one of the magnets and make a special jig to zap them one at a time.
No two magnets are the same so when you zap both magnets in a can to their 100% potential that doesn't mean they are equal just that they are as strong as they can possibly be. One magnet usually reads higher with a gauss or tesla meter.
As for changing the timing with a magnet zapper. Yes its fairly simple and can be done. However I know the florida series and some of the big races have already banned the use of the technique. I was told they are no requiring the center of the magnetic field of both magnets to be in the center + or - a given amount.
In testing though, increasing the timing on a motor via changing the magnetic field hasn't really been of benefit. The only place where it seemed to be an advantage was in some of the 0 timing spec oval classes. In touring applications it just makes the motor run that much hotter and although it may gain you a tenth up front most people will lose 2-3 tenths in the last couple of minutes in the race.
