[Healeys] Strange happenings

[Tom Felts]

Went for a drive in the BJ8 today. Running along a smooth as silk.  Got a few sputters, then a backfire that smooth.   Shortly after, same situation.  Then it was like someone turned off the key.  She died.  Waited a moment she started.  Smooth for a few seconds, then died.  I found the fuel pump was working and I had fuel to noth carbs. Checked both float bowls, full.  Checked grosse jets, not sticking.  No overflow fro manifold or carbs. Kept the start/shut off and would never continue running.  Called AAA, got towed home.  Any ideas??
