Robin, to get good amplitude there is not a adjustment that you would do to the suspension spring. Do a search on this forum or a google search on floating balances, there is alot of good information out there. ALSO, try a test, take the floating balance out of the movement, mount it in a vise and turn it almost 360 degrees, let it go, should run for 2-3 minutes. Also, with the power down on the mainsprings, remove the lever from the movement, give the time mainspring a couple of clicks, see if the time train moves freely. A picture of your movement would be helpful.
Have a great day, William
