RE: Official Nitro Evader ST Thread v2.0
I got the actual break-in from duratrax last night and will add it in above in the first post.
1) Put the fuel in the car (make sure to use something with at least 18% lubricant).
2) Make sure that you have fresh batteries in your transmitter, receiver, and glow starter.
3) Turn on the transmitter and receiver.
4) Make sure that your high speed needle valve is set at about 2-1/2 or 3 turns out from close.
5) Your carb should be open about 2mm. You may need to adjust the idle screw or the throttle trim.
6) Put the glow starter on the glow plug and lock it on by slightly turning the starter.
7) Pull recoil with short quick pulls. (May take up to about 25 quick pulls to start)
8) Hold the car from moving and pull on trigger and release, car should try to move with out stalling.
9) Remove the glow starter and start driving either back and forth or in a big circle. (You will need a large area so that you will have plenty of room to open it up all the way with out hitting something.) Vary the throttle making sure to open the it up fully at least part of the time.
10) Your car should be rich and you should be seeing smoke coming out of the muffler or tune pipe.
The car will also seem slow or "dogish." (That is normal during break in)
11) Make sure to let your engine cool for 3-5 minutes between tanks. ( For the first 2 or 3 tanks do not fill up all of the way, ½ to 3/4 will be just fine)
12) After the first 2 tanks you can start leaning the engine (closing the high speed needle). Each tank you should lean it 1/8 of a turn until your car is no longer "dogish" and is starting to sound right.
It should only take between 6-10 tanks of fuel before it is fully broken in. Your needle will be around 2 turns out from close but it will vary depending on the engine.
Do not let your engine run at idle for very long until it has been broken in completely. Idling during break-in will cause the parts to break-in at too low of a temp and will cause eventual failure when engine gets hotter.
