Hey guys, having some problems. I have a traxxas .15 pro engine and i just cant get the thing set right. Heres whats going on. The thing takes at least a good 15 minutes to get started. Once i finally get it going i have to rev it up or else it will just stall. Once it is finally hot it idles very weird. It will idle really high! then if i slam it into full throttle and let off, it will idle normally. Then again if i only go half throttle and let off it will idle high again! Anyone know what the problem could be? Any help would be greatly appreciated.
