I use Powermaster's YS 20/20 fuel in my OS .46 AX and it turns an APC
11x5 @ 13,200 ~ 13,300 RPM (static) at sea level with the needle 3-4
clicks on the rich side of peak.  No modifications, shims or anything
and I'm using an OS A3 glow plug.

I really like the 20/20 fuel because it runs well in all my engines -
and that simplifies what I have to haul to the field.  Some engine
manuals recommend a head shim for fuels above a certain % nitro, but so
far the only one I've added a shim to is my Thunder Tiger .36.
