Default Os 70 Surpass Runs Eratic At Full Throttle

NOTICED JUST NOW I SHOULD HAVE POSTED MY QUESTION HERE.. ANYWAY I HAVE A NEWER OS 70 THAT RAN FINE LAST SEASON, BUT WHEN I TOOK IT OUT TODAY IT WOULDNT RUN RIGHT. STARTED UP WITHOUT A PROBLEM AND IDLED GREAT, BUT AFTER HALF THROTTLE IT STARTED TO ACT UP. I MESSED WITH THE NEEDLE ALOT WITHOUT MUCH RESULTS. I THEN LEFT THE GLOW STARTER ON AND IT RAN MUCH BETTER BUT STILL HESITATED A BIT AT FULL THROTTLE. IM USING 15% FUEL AND A FOX MIRACLE PLUG.. ANY SUGGESTIONS AT WHAT ELSE I CAN LOOK AT? COULD IT BE THAT THE ENGINE IS GETTING PICKY ON PLUG TYPES?

Yes, feed it an OS type F and I suspect that with a little tuning it will calm right down.
