Dissapointing performance

Have any changes been made to the current set-up since this thread started?
I put stiffer spring to distributor. I made new one today that is stiffer and it should be stiff enough to give full advance at 2200-2400. Also I have made compression test, but only for one cylinder. If I have free time on weekend then I do test to all cylinders.

Bigger update for parts isnt coming soon. Maybe not till next winter when car sits in garage.
