This has me really confussed. I have Pertronixs in the dizzy and a MSD Blaster 2 Coil, Carb conversion from FI, '74 four. It runs great as long as the tach is disconnected at the coil. If I plug the tach into the negative coil terminal the engine will start, run normally and the tach works perfect at all RPM's. But after running only a few minutes the engine shuts down and will not restart unless I disconnect the tach wire from the coil. Any suggestions would be really appreciated, thanks.
