So I got this jatooffcraigslist abouta month ago and every thing was great, good compression and all the other things you look for when buying a used nitro. Every thing was running great up until I switched out the spur gear frpm a stock 54 t to a 58 t and I messed with the tuning abit, now it runs well but gets very hot I've seen it reach temps of 400f + just before it cuts out. Now its deffinitly not to lean,if anything its to rich I have it set at 4 turns out. For example starts right up when cold and idlesgreat, once it reaches 230f it idles higher and jusr keeps increasing the temp until it shuts off. I'm lost....HELP!!!!
