coil trouble??

Doesn't really matter, they're all the same. *Coils do run somewhat hot. *Most coils are designed to run on ~9v, not 12 because they are run in series with a ballast resistor. *If you have converted to electronic ignition and have removed the ballast resistor, you may want to consider an HEI type coil or some other performance coil designed to work with electronic ignition and 12v.
