Hot start problem. Rough idle and Tach jumping.

I installed the new MSD Coil today along with new ends, soldered, to all the wires, to the Coil. This new coil seemed to do the trick. I took it for a twenty minute ride, then shut if off and waited 20 minutes before restarting. After 20 minutes it started instantly and ran perfect. It turned out to be the coil after all Pha Pha.
