RE: What size of a magnet do I need for CDI

I bought a pack of 100 AlNiCo magnets from an electronics supplier in North Dakota I think it was. They are .250 long and .125 in diameter. You may try CH Ignitions as I think they sell them also. Not real expensive but I do a fair amount of engines and repairs so I found it cheaper to by in bulk. I drill a .125 hole in the tining ring and JB Weld the magnet in. Never had one come out. Some will stake it in with a punch. Can't get ot out as easy I have found. Just pass it by your sensor and make sure the end that fires the sensor is facing out or you will not get spark.
