      Default 4160 accel pump setup

      I have a 1996 holley 600 vac secondary 4160 carb. I have a higher lifter cam heads etc. So I moved the red factory position to 2. This seemed to make it more responsive in neutral and got rid of bogging after 30 feet and now skids sideways 2 feet when it hits second on the c4 but town driving a small hestation off idle.
      I adjusted to .015" at WOT now in posution 2 does not move the cam untill 25% throttle.. cant adjust tighter as will bottom out the pump and spring on bolt will be loose.
      Do I try different jets on the squirter or what to do?
      I have a 6.5 power valve need to put in a 4.5 for my vac of 9" in gear(auto)
      Any advice?
      Thanks!
