I have a ofna nexx 8t with the force .32, It is pretty new, maybe a quart or two past my break in. I leaned it out a tiny bit and it has a beautiful stream of blue smoke all the way to hitting its top speed. But my temps are quite high, the couple runs I did with the leaner setting I saw 240-250. After a day of sitting I took the glow plug out and it too has fuel on it so I know I am not running lean. Could this problem maybe be caused by bad fuel? I am using o'donells racing fuel (the one in the white bottle). I bought it from my lhs and have no idea how long its been sitting, the lables faded quite a bit so I am guessing its been there a while. No love around my parts for nitro lol.
Any help would be awesome.
what is the oil/nitro content ? if your running a sport fuel with high oil its going to run very hot as opposed to a race fuel with lower oil.........Lower nitro/high oil fuels will run even hotter ..... something like 20/12 will run much hotter then something like 30/8 ............
