Default os .25 FX questions

I recently bought a .25 os Fx. After i burned it in with about 12 oz total of very rich running i went flying with it and have so the last couple of days. While i do appreciate the ease with witch it starts, it seems to me that i can't get it running supersmooth....I had one deadstick in 13 flights or so but what struck me was the trouble it took for the engine to rev up when it had been flying on idle for a while....Is that normal???? Only when i leaned it out enough (the flight it went deadstick) it seemed responsive like it is on the ground.


The prop is a 8-8 graupner because the rotor-ground clearance isn't enough for a 9-5 or 6

Tank is placed right behind the firewall with all new tubing (except for the fuel filter)

standard muffler

Is it the prop?
Is it not "burned in enough"?
Has it got something to do with the low rpm needle on the carb. (i don't know what to do with it)
