When you say "Installed new mainspring" did you use a vintage Gruen blued-steel spring or a new white-alloy spring? If blued, then it is possible it is also set. What size/length did you use? Could be too long and thus not fitting the barrel correctly.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
