How to tune a nitro?
Im new to tuning nitro and have some experience with 2-stroke tuning. My questions are:
1.Tune in what turn increment?
2.Digital temp gun the best way to check the engine when leaning?
3.Maximum safe temperature for a nitro engine?
4.What is the danger temp zone?
5.Recommended brak in process
Notes:Will be tuning Traxxas Nitro Rustler

1) 1/8 turn is what I use, after that I just nudge it to fine tune it.
2) Or you can spit on the motor, if it boils off quickly, it's too hot, if it just sits there, too cold.
3) Highest I've heard is 260-275.
4) anything higher is too hot.
5) Idle for a few tanks, then a few on light throttle, then a few full throttle ones (how you would use it normally, say, in a race). Varies from engine to engine.

one last question. What is the farthest you would want to make a turn (needles) from the factory settings?

One thing I have learned which i will share is dont get into tuning to temperature..if its cold does not mean you can lean it out, if its hot dont always mean its to lean. watch you exhaust smoke and pay attention to your idle, and your engines performance. those are the most important things. check temps just to make sure you are safe. if your engine is tuned perfectly it will only run Hot or cold if there is a problem! air leak, clogged area, dirt inside, bad bearings, etc. temp is more of an indication to other areas. Smoke first, performance second, temp last
