top cylinder constantly miss fires.. changed everything three times swapped everything three times... been working on this for months and it still has a miss.. tried three different sets of points, condensers and coils tried a different mag plate that is way tighter... swapped everything from one side to the other.. changed the wires... new crank seal... and the top cylinder will not fire a constant spark.. I hook my timing light to the bottom hole and it's perfect.. hook it to the top hole and it randomly lights up.. I'm at the point of smashing it with a hammer I just don't know what else I can try.. Never in my life has anything kicked my ass like this, I've been twisting wrenches for 40 plus years,.. what am I missing here..
