I bought a firestorm 10t mid week, i broke it in and have used about 3-4 tanks but i find it really hard to start up, i have to put some throttle on to start it up and as soon as i take it off it will stall, it wont start with out throttle, i haven't done anything to it to the needles and when i start it with the throttle on lts of orange stuff comes out the exausht. But it wont start with out throttle and it has to be moving or it stalls, i'm really new to these cars and not too sure how they work, any help would be much appreciated.
