Engines Plugs Mufflers Fuel > Os50 engine woes

Hi guys,
Well my os 50 ran great the first 5 gallons of fuel in my Fury. Upgraded the Fury to a 60 and put the 50 in a Sceadu. Since then I have had extreeeeemly sensitive needles. In fact its worse than that. I have not gotten the engine to rev up to operating speeds at all since the move. When I throttle up, it will go from chocking/bogging rich one time, to what appears to be a lean cut out the next. Ive tried needle settings everywhere. What could I be missing?
This is what Ive tried:
-2 different mufflers
-checked for air leaks in engine, carb and fuel line
-header tank
-dissasembly of carb/engine
-glow plugs
-fresh fuel, I use redmax 15% BTW
Thanks for any help,
Justin

hows the weather out in hilo? try 30% and adjust your throttle curve for 1900 to 2000 rpm. The 50 should run at 1 1/2 turns out on the main, give or take a 1/4 turn

I've heard the stock fuel tubing in the tank is too soft and can collapse. You might try something a bit stiffer.

Don't I know it. I suffered 3 inverted flame-outs because of the stock clunk tubing which is the same on the freya.
