I HAVE ONE OF THESE TRUCKS and it runs great. a friend of mine just got one but is having a problem with it. it runs fine but will not move. he says that black dust is covering the engine and air filter and is basically all over the chasis. i havent been able to inspect it personally but am thinking that the clutch may have been burnt up. being the truck has only been run an hour i find that the clutch failing to be unlikely but maybe it was just a bad one to begin with. does anyone else have any other suggestions on what it may be? or does it definately sound like a bad clutch? just want to be sure we are on the right track before i go getting him new parts. thanks for any ideas..[8D]
