Ok, So it looks like the pipe in the truck is this one
http://www3.towerhobbies.com/cgi-bin...&FVSEARCH=4942 which i think is made for the .15 engine.. could that be the trouble? my friend who sold it to me says the pipe is too small so makes too much pressure in the fuel tank, which makes it run rich... I have no idea if thats even possible.... (I havent even tried starting it again yet....)
