You shouldn't have a PV on the secondary side. The PV is on the primary side. The primaries should be 6-8 jet sizes smaller than the secondaries. You really need to put the carb back to square one and start again with the tuning. Using the same jets, front and back, won't make it "square" You still have the PV in the equation, that's why the Primaries and smaller than the secondaries, to allow for the 6-8 jet sizes the PV compensates for.

If you have 4 corner idle, all screws should be out the same distance. Use a vacuum gauge to adjust for highest idle, then add 1/8th to 1/4 turn, other wise you'll be to lean. Go down in size on the primaries, until you get a lean surge. Don't open the secondaries. When you get the lean surge, go up 2-3 jet sizes. Then add 6-8 to that number for the rear, and see what happens. You should really be doing this with an A/F meter.
