Doug, my Zerostat never did work right. I managed to get it open, I discovered the two halves are not glued together.
Inside is a small cylinder with a lever connected to it. There is a locknut that is used to set the adjustment on it. I found there is a very small area in the adjustment range that makes the thing work.
In the end, I was unable to improve on the factory setting, which only works every third or fourth squeeze of the trigger. Yours may turn out differently, but you won't know until you try.
Best regards,
Dan
