Greetings, 
     While not the factory suggested procedure, I have had success with 
turning the rack upside down, and regulating the springs so that they have 
just enough power to suspend the underlevers approx. 1/8" from the rack.  
This provides a little more spring on the heavier weighted underlevers.  If a 
 spring is obviously too strong, it is a simple matter of pulling the 
underlever down to bend the spring, which will ease the tension, but be 
careful, it is easy to overdo this.  
   For eveness, I bump the rack up and  down so that I can see any 
underlevers that fall more than others.  I get a very even spring load this 
way, and everything has functioned well, (7 installations, so far, I think.)
