Dissapointing performance

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 isn coming soon. Maybe not till next winter when car sits in garage.

Is that the direction that you want to go in??

Stiffer spring makes it advance slower...

Lighter spring makes it advance faster...

You must be kicking the advance in too fast to cure it with a stiffer spring...

Usually we want to kick it in faster and use a lighter spring...
