Taper didn't change it much. I tried from 182-190 main. 188-190 is it's sputter point on top end. 185 clears up nicely, but I have 182 in now. May go back to 185 main. Needle N3EW 2nd position Pilot 55 about Power Jet 55 Air screw .75 turns out VP C12 with Redline 48:1

My buddy Terry started this thread. His 350 is still running strong. I've never seen him have any over heating issues.
