Hello,

i bought a OS46FX for my Dazzler I just finished. I followed exactly the break in instructions in the manual. However after running 3 tanks on the ground i brought it rich in the air. Under rich setting, the throttleresponse was really delayed. well i thought let's keep on going. Now that I have almost 10 flights and the setting are leaner, I still have the trouble of delayed response, especially when I start (I ease in throttle, Although I am at full throttle, the engine only gives 50% . after take off (still full throttle) the engin start sppeding up) Trying to accelerate out of slow flight shows the same.
experienced guys at our club helped me to adjust the valves: the high speed is about 200-300 rpm below max. the mixture was at factory set (1.5 turns out) and at lean set (about 1/8 turn to rich after engines stuttered to speed up)... no difference same trouble.
It also looks like that I do not have these problems to this extend while the plane is NOT moving. When i lean it out to get fairly quick response at start, it'll die in the air.

Any ideas?
