Hey guys, just earlier I started up my .15 nitro 4 tec and I'm having issues with it at idle (and most probably low speed + high speed too, but I just want to fix idle issue now). When it starts it idles normally, maybe a bit high on the revs side; and then I see the fuel going to the carb then all of a sudden rpm shoots up and the wheels spin at full speed. If I brake it stops the wheels but revs are still quite high. I'm pretty sure I've set the idle screw as far back as it can go.
