misplaced, see if the A7 has a floating center pin in it and if it does, try pushing it down a little. I have a AGA-T that I was having the same issue with (would not fire on my Provari). Once I pushed the center pin down a little so it would make contact it started working like a champ.
Just wish I wasn't 2 hours away from ya cause I think I could have ya blowin clouds in no time.
The A7 has a threaded center pin which can be screwed in or out to insure proper contact.
