Ignition will not fire until it just passes the magnet. I drill and press it in with a drill press and put some epoxy in the hole. If you drill it to big then you will need to punch it with the point of a tap or something sharpe. Punch it in four places around the magnet (12 oclock 3-6 and 9 oclock)
I might have a pic i will have to check and see.


Thanks
