Just got it back together.. same thing.. nothing has changed...... (1) - lift up or push down on the mag or ignition plate and it coming into it, runs fine, let go of the plate and the top hole miss fires.. I have changed the ignition plate and it's mount , coils, points, condensers, everything 100 times... (2) - maybe the coils are hitting the magnets I can't move them back any further without having to drill out the mounting holes..
(1) - Now, there's something I don't recall reading previously, and obviously it's something that would affect the point setting and the top cylinder. That ignition plate (Armature Plate) should not move either up or down. The cure follows:
********************
(Magneto Armature Plate)
(J. Reeves)
If the armature plate has a a loose fitting, wobbling motion (the plate that the points, coils etc are attached to), it is usually caused by a slightly worn support ring. This allows the point setting to change erratically as the armature plate turns.
The cure is to remove the armature plate so that the support which is attached to the powerhead with 4 screws is visible. Then, with a screwdriver and hammer, or some tool of your choosing, and looking straight down at the support ring, make a slight indentation at what would be called the 12, 3, 6, and 9 O'clock positions. Install the armature plate and check for a smooth turning wobble free movement.
You may need to do that procedure a few times to obtain the proper fit (not too tight, not too loose), but it's worth the effort.
Use a small amount of anti corrosive grease between the aluminum ring and the brass support plate and also on the brass bushing of the armature plate when all is well.

And as for where the coils belong, see below:
********************
(Magneto & Driver Coil Alignment)
(J. Reeves)
To align the coils properly, have the metal vertical portion of the coil yokes aligned with the inside edge of the bevel that exists on the top portion of the aluminum seat upon which the coils sit. This creates the proper distance between the coils and the flywheel magnets. Faulty alignment creates friction and the yokes of the coils heat up, turn blue and expand.
