Hi EWhiteWatch,
I just read the part of your first post where you say

No matter what I do, it does not seem to make any difference

does this also include adjusting the regulator? If you’re getting little or no change then you may want to check the index pins again. I know that you mentioned that you adjusted the regulator pins but just in case check again that the pins are not too far apart. The hairspring must contact “both” pins during vibration. Changing positions will often reveal this problem. There should be very little space between the hairspring and pins.

Bob
