Hey guys,
Need some tuning help. I have 9 tanks thru my Orion .24. The idle is consistent and perfect. I used a heat gun to bring the motor up to 200 degrees before I started it every time. I idled 4 tanks with the head taped, and idled it at 210 degrees, tank 5 thru 8 figure 8's on the ground(dirt) with tape removed. It was very rich, barely gets going at all, made sure temps were 200-220.

Tank 9 started to lean out HSN, I am 2-1/4 turns IN from flush!! LSN is slightly in from flush. BTW, its 85 degrees here in AZ today, but that still seems like too much. It accelerates pretty clean, still sounds a little rich. Good smoke trail. Definately coming to life! It sounds great and temping at 238.

What's up with the HSN? Should I leave it? I was going to put another 5 tank through it tomorrow night at about 50% throttle on the track and then step up to 80%.
