This is driving me nuts. 1964 3HP JW19A. The problem is that the top cylinder is the only one that fires. Both coils check out OK. I have swapped coils, condensers, points, everything. It does not matter.
I am turning the flywheel by hand, and the top coil produces a great spark - no problem.
The bottom will not fire.
I have swapped out everything, sparkplugs, coils, points, condenser
I have wrapped both wires with tape - no difference.
It seems impossible. I can swap everything around and it makes no difference.
If I check the spark by placing a screwdriver in the spark plug boot and holding on to it and then turning the flywheel by hand, both wires seem the same to me - it will shock you quite well.
