my rusty wont tune i cant get it above 200 without the body yes i know how to do it i lean the hi speed out and i floor it then it stalls. so after trying over and over again with that. i tryied riching low speed a 8th of a turn then a half turn leaner on hispeed that dont work either same thing happens... but if i run it rich its fine

Have you tried restarting your tuning from factory settings...?

If you are taking the temp with a temp gun, and if so where are you taking it at. You should be taking it from the glow plug area down through the heat sink. Also I believe that some temp guns also have two mode's. If your on the wrong mode then you will have some reading that will not be accurate an there fore making you believe that it's only at 200 when it could be at 240 or 250 so make sure that thats not it. Try those then get back

yeah i know and the temp gun is right because my buddy has a revo t maxx and gt and it works fine on all his plus i tried his gun but thanks for trying... and adio i have restarted manytimes

Well some engine's run cooler then others. Now I have never come across a engine that has run below 200 degrees. But if your enigne likes to run cooler then others then thats that and you cant really do much about it. But I alwasy say not to tune for temps but 200 is extremel low but if thats what your engine's sweet spot is then thats where it is. Thats about the only real further advice that I can give you at this point.

Is this a 2.5 or a Pro .15 or what?

Pro .15 stock is low speed flush and high speed 2.5 turns out.

2.5
