no spark eh?
check power to the coil.
sound slike you should be using the oem ballast resistor plus another one if you are also using the oem 6v coil.
check to see if the poiunts have closed up.
put a test lamp inline with the coil. run engine over. should blink.
if it stays on.. you have a short in the dizzy.
if it never comes on.. points are not closing electrically.
improper, too close, points gap will show as burned points.
open condensor will show as burned points.
shorted condensor shorts points.
