I dont know if this should be posted here... But my nitro car has lost ALL its engine power, it was running fine a few days ago, then i put some 20% in (because the previous owner run that through it). It ran two tanks perfectly then the next day it lost all its power, i have a video (link below) for you to see just how bad it is... Please help!

P.s In the video most of it is full throttle, and at the end when it goes fast its because its going down a hill.
