I have just got back into the hobby after a year or so, and when i tryed to get my Nitro mt2 started, it started and when i gave it any throttle it would cut out dead. And when i would pick up the car to inspect it, there would be lots of fuel run out of the exhaust. A trip to the local hobby store, and 2 litres of fuel later, i runs like a charm, former glory. I would recomend getting new fuel before you start to run any cars again. Hope this helped.
