where is the screw and wat is it supose to be set to? pics would help

 

Ive posted this probably 5 times in the last 2 weeks. The idle adjust screw in on the back of the pump. You wont be able to see it unless you use a mirror. its just one of thos things you have to do blind. It really helps if you have long arms, and a stubby 10 mm wrench.
