i have a winner one as well and my carbie has three calibrating needles also wich i stuffed up also. So what i did was tighten all the needles to full then unscrewed the main needle 3 full turns then i unscrewed the idle screw two full turns (with needle try to NOT let the throttle pop out, though it is easily fixed) then with the last needle i set it about half way out. this should get you started then once you have the engine going tweak it up from there. P.S when you are "tweaking" and the engine stops just put the needle back to the position it was in before it stops.

i hope this helps and good luck

P.P.S my smartech car flies i race it on the weekend at my local track and generally win most weekends unless i have a smash or somthing.
