It does sound like you're too rich on the bottom, though...I'm at 2700' and have a 45pj, 162mj, 04WR needle on the middle(4th) groove and functional ACV. Stock exh. w/GYTR insert.
3 turns out on the fuel screw(which IS the mixture screw...)is too much, they've been lost with 3 turns...
Should I be able to snap the throttle open from idle' or just above idle without it bogging, and stalling. Have all the free mods and GYTR insert. Current jetting is 50 pilot, 162 main, #5 groove, 3 turns out. I had the carb off and the a/p seems to be pushing enough fuel. I am saving for the JD kit, but want it to run good for now. It runs great if I quickly roll the gas on, but falls on its face if I snap it. Any help would be appreciated.

well we need to define whether he is talking about the pilot screw which a lot of people call the fuel screw or the idle mixture screw, either way 3 turns out seem a bit rich, my pilot screw is only 1-3/4 turns out.
Ok...where is the "mixture screw"? The pilot screw is the one Zip Ty and everyone else makes a replacement for, correct?
