everything was fine this morning,start smoothly,excellent idle,the car was fine.Now,the idle is to high,the wheels spins.Everything goes wrong like 2 weeks ago and brought to my LHS.It cost me 20$ to fix it.I want fix it by myself,but i dont know where to start.Did i have to adjust the engine with the radio and the car ON or OFF.I got a Super Nitro Rally with .15FE.I got 2 needles.One for the lean and rich and an other one for the idle.I turn every screws and i dont know where i'm going with that.How do i have to start.3 turns for the lean and rich needle but the idle i dont have any idea.The only thing i do today is changing batteries on the car and radio so i had to dissembled a part of the car.But i dont seems to change any setting,i be very carefull.

The guy from my LHS come back just monday and i want it now!If no one help i'm gonna have to wait all the week-end.I'm very newbie in this hobby.I'm afraid to burn the engine cause he run so high when i start it,its crazy.
