RE: Problem with Ignition System
Yes, the orientation of the magnet does make a difference. I think 3W now makes an ignition that has two magnets in the hub one with the north pole exposed and the other one with the south pole exposed. The ignition picks up both magnets and can use this information.
Another thing I learned the hard way if you heat the hub with a torch, it destroys the magnet. Apparently heat can ruin a rare earth magnet.
