I have a VX 18 on my truck! For some reason, when i start the engine, the wheels are turning! I was trying to get the idle down, but still! Which ways do I turn for idling up or down and how to adjust the low speed needle. The low speed needle is flush! I kinda know how to adjust the high speed needle! What would be the problem, when the truck is almost out of gas and it is going full speed?When I was doing break in, this is how I destroyed the front bumper, the steering servo and arm![] Does any body have a user manual for VX 18 engine? Cause I got my truck will almost no instruction manual![&o]
