NEED ASSISTANCE: My son just purchased a Mayhem ST RTR. He has run about a tank thru it, so far. It wouldn't start yesterday. I am into RC planes, but know nithing about RC trucks and my son is brand new, too.

In reading the manual it says: "When checking the adjustment of the low speed needle, it is crucial that the throttle
slide is closed completely and that you do not over-tighten the needles."

The carb slide is open approx. 2 mm, which I assume would be about "idle" position. Does the slide have to be "completely"
closed with no gap showing before you adjust the needle? On air engines you adjust with idle setting about 2 mm open.

For my planes, when I bring throttle stick to "0" this is idle. I use my throttle trim to "kill" the engine. Stick at zero is idle psoition
approx. 2mm, then trim closes the barrel completely. How do you set for this truck?

We would certainly appreciate your input for a couple of real beginners.

Thank You
