I just learned from another forum to buy Ace Hardware spring# 144 to replace factory spring. With no adjustment or spring at full length, should get 1.75 lb to 2.00lb. Tighten spring and should get 2.00+ that I am looking for. I bought 3 Ace springs today at .69 ea. I won't be installing for a month or so by another club member friend that has all the tools.
