Estang,
Try adjusting half as much.....1/32.
Some of these are a wee bit touchy in adjusting.
Be CERTAIN all such adjusting is with the eng warmed up.
You'll get some black goo residue for about 1-2 gallons of fuel,
but it'll become less & less as the eng breaks-in.
Estang,
Your welcome. And yea, what he said. Just keep it on the rich side.
As for the rpm, 8500 is a bit more than what I believe you should be running WOT. It will unload in the air. I try to keep mine closer to 8000. I'm running a XOAR 17 x 6 at 8100 rpm.
