I am doing the first step of idleing my engine for 2 entire tanks but after 2-3 minutes of idleing the enigine slows and 5 seconds later cuts out? The cooling head is EXTREMLY hot and i think it might be overheating but i am not sure, I also may have to adjust the idle knob but in not sure which way, if anyone has any ideas they are much appreciated.

it shouldnt overheat when just idling. i know that the go engines are so tight that its kinda had to idle those at first. you should really invest in a temp gauge.

and yea sometimes you might have to turn the idle up during break in so the motor doesnt die

Just crank your idle up... If its extremely hot it may be too lean... Did you mess with the needles? To turn your idle up turn the IDLE screw clockwise (screw it in) If you messed with the needles at all you may have your bottom end to lean... Which would not be very good on a new motor... lol i had my GO idle through 2 tanks without a stall... VERY rich.. What kind of engine is it?

You dont NEED to idle it to break it in... you can slowly run it at half throttle for a max of 3 secs, should give same results and also won't superheat it
Idling will eventually flood the engine with fuel... that's why it dies.
using higher idle will make your car start moving.
just use half throttle to break it in.

i usually idle mine on the starter box for a tank or 2 then i set it on the ground and go from there

It would be a good idea to get yourself a temp gun too. The motor should be at around 200 degrees during break-in usually.

Grab your manual, check what your needle settings should be, and then reset your needles to the factory settings, including your idle.
There are a lot of different ways to break in your motor, from idling, to the heat cycle method. With modern ABC (Aluminum piston, Brass sleeve, Chrome bearings), the old school method of idle break in, is not the best way to break in a motor anymore IMO. Check out this thread: http://www.rcuniverse.com/forum/fb.a...Cycle%2CMethod
World champion drivers use this method to break in $1000 motors.
I and many others have used this method with great success.
Choose what you think is the best way for you. Good luck.

Thanks for all the great tips guys, apreciate it. I am some what new to r/c and I dont want to wreck my brand new buggy.

It is a .21CXP engine.
