I recently purchased a used nito rustler and am still trying to get it tuned right. I can get the high speed needle adjusted corectly but the low end is a different story. I did the pinch test to check the low speed needle and it runs for 6-8 seconds before cutting off. I tried adjustling it and making it more lean, however, the low speed needle is screwed all the way in and isstill too rich. How can I solve this problem? Also, the car is having problems idiling. The guy at my local hobby store told me to adjust the low speed needle and that should fix it, and it didn't. I tried raising the idle speed screw and the trim on the transimiter but no luck. When i bought the car I purchased all new batteries for the reciever, transimiter, fuel, glow plug, checked my wires, new air filter housing and new fuel lines. I am stumped and any help will be greatly appreciated.

Check the carb internalls. Refer to the parts diagram for the engine you have. Make sure there aren't any parts missing and that the carb is assembled correctly.
