318 cuts out when revving

If you hot wired the system direct to battery and you are sure it's getting power there's only three things I can think of..........

Somehow the Pertronix system has a problem

The distributor is worn out and stopping the Pertronix from triggering........shaft play, etc

Or a bad coil

The only other factor is "what all" as in "what else" do you have hooked to the coil..........a tach? UNHOOK it. Radio noise capacitor / condenser? UNHOOK it. Get it down to only the distributor, Pertronix, and coil.

By the way check your "hot wire" I've had trouble before with bad alligator clip leads, AKA radio shack[/QUOTE

Ok thanks . We have no radio or tach.
