Got Smoke?

Posting this here because I know I won't be able to reach anyone in the office until Wednesday. I am trying to fine tune my newly rebuilt 12V engine with a benched ppump. I'm waiting on some parts I ordered to install a FP gauge. I read in the owners manual for my AirDog II 165GPH that you can get the pump in 30-35psi range by backing the regulator all the way down and then turning it clockwise 7 full turns. Mine will only go in 5.5 turns? Truck definately runs better, but I find this odd that it won't go as far as the directions state? :what:
