Just restored an IB and now I don't have any spark. What could be the problem ?
Got the mag off, and it doesn't give much of a jolt when turned by hand.

assuming the coil in the mag was good to start with, the normal problem wiht loss of spark is poor electrical contact. this can be caused by
--points are dirty and need polished
--wire on the point is touching (grounded) to the case.
--you left the fiber washers off and wire is touching ground
--there is a #10 small stud sticking thru the case to the outside. grounding this screw grounds the spark and kills the motor. if it is touching the frame, or bad wire, you get no spark. these are the areas to look first. if you have a "weak" spark, things could just be dirty, or coil going bad.
