Many thanks for the replies. Let me be a little clearer. The timing is set at 6 degrees BTDC with vacuum lines to the Loadomatic plugged. When I reconnect the two vacuum lines, with the engine still at idle, the timing retards into the after top dead center region. Revving the engine does not move the timing mark. I see Sal's point that revving in neutral won't advance the timing. Is it the case that the Loadomatic retards the timing at idle to avoid "ping?" I've had this car many years and never really looked into this. If this is correct behavior, then my other Loadomatic unit was OK.

The problem I've been chasing is this. The car will accelerate to say 40 mph smoothly. Then, if you squeeze the accelerator slowly, the engine just sits there at the same rpms. If you pump the acclerator a few times, the engine will respond and the car will accelerate as it should. I've never had another vintage car do anything quite like that. It's the old "carburetion or ignition" issue.
