Don't base all your decisions on temperature. As long as the engine is making the correct sound and you still get a nice stream of blue smoke when you get on the throttle you are probably well within good running conditions. I would really only be concerned if your engine started going towards 280-300, then I would start to look for things such as air leaks.
i'll tune it by ear, and even with a nice smoke trail, i'll bring it in to check the temp and it'll be climbing past 280. but if i have it tuned to run around 230-245, it runs too rich and won't rev up like it should, or is slow to do so. so that's why i was wondering what plug you guys were using. i can't remember what i put in it last time, so i was just going to buy a fresh one, and i'm out of fuel, so mabye i'll try going to a race fuel, and hopefully the temps will be lower. even the low end likes to run fat.
