AND NEVER EVER FU(KING TOUCH THE MIXTURES WHEN YOU GET IT FROM THE FACTORY!!! THEY ARE SET FOR BREAK IN!!!
The manual has them set at BOTH 2 turns out...
Get your needle, turn the mixture fully clockwise till it stops (DONT USE MUCH PRESSURE)
Then count near on exactly 2 turns anti clockwise...
The problem you are having is TOO MUCH fuel when you accelerate...
Also changing Nitro % is fine, my advice would be when changing any fuels over, make a mixture up of 100ml of one fuel, with 100ml of the other mixed togethor, shake them both togethor, and use that all up before running the second fuel... (Something i do so its not a sudden change over)
My GS-15 had 4 turns on the high speed needle and the low end was flush with the carb !!!
I changed fuel a few months back!!all i did was run the motor on factory settings for half a tank then raced tuned it and checked the temp every couple of minutes.
