I have bottomed the screw out turning it clockwise, and backed it all the way out. No change in idle when moving the screw.

Hmm thats real odd well just wait till you get your 3200 rpm spring at that time you will be able to see whats going on inside the pump in that area the rpm spring is going to be one of your biggest difference you will feel

I got the pump taken apart and the new spring installed I ran out of daylight so I didn't get it all back together but I did get some pics. Everything is clean and looks like new nothing worn or broke that I could see. Everything to me looks the same as all the pumps I have seen online. I will post some pics
