MSD Disappointment ??

The only time I had an issue with an MSD was I didn't have 12volts in the START position. SO whenI did my testing under the hood it all tested out ok.

I've had a miss once, which was a bad plug wire that got burned by a header.

I'm a little surprised you bought a 6AL plus the timing start retard. The Digital 6 has both of those features built in
