I know exactly what you mean. Mine does that sometimes, depending on 
how it's loaded. The simple solution to your problem is to change where 
in the rpm range that spot is. This can be accomplished easily if you 
use the  140 linkage that comes stock with springs that activate the 
secondaries. Typically, you will have replaced those springs with a 
solid piece of tubing - brake line or fuel line tubing; can't remember 
what I used. Now, by simply changing the length of that tubing I think 
you'll change when the secondaries come in. You probably want to cruise 
on the primaries in which case you should change the length of that 
tube so that the secondaries come in later, thus allowing you to cruise 
on the primaries. I haven't done this, but I think it'll work.
