I am running a NECJ at mostly sea level with 172 and a 40 pilot in summer on clip 2. Clean crisp with barely a dribble out the pipe. Remember there will always be some spooge out the back. You never want to have nothing, it is lubrication after all.
I only tweak the air screw with a 42 pilot in winter. Having the squish set and compression lowered helps massively with knocking and pipe bang.
