Hi guys..I am desperate for some set-up help. I bought my new 63FZ run a gallon of YS (model Technics/UK) fuel through it, but CANT MAKE IT WORK PROPERLY.
Full throttle is fine.. idle is fine...mid range is fine...all this for the first 2 minutes. Then if i close the throttle on flight, the engine is dying very slowly.What i mean is that by puling back the stick, thats it! No response after that no matter what i do.
It revs on idle and by increasing or decreasing the throttle there is no change...
Is this too much fuel on idle? is it to lean on idle?. Maybe mess with the regulator??

Help please... I bought a Flip 3d and i am now thinking of changing to my OS 50 as i NEVER had set up problems...
By the way this is my 1st YS..
