Pilot screw after BK Mod YZ426F

I installed a 168 main and a 42 pilot as per the BK mod. The mod instructions say 1 3/4 turns out on the pilot. If I go out that far. My pilot screw is not snug...Is this ok? I'm barely snug at 1 1/2 turns out...Please help. Thanks

check to see if it has a spring, a washer, and an O-ring on it (from bottom to top)
