i am running a sirio evo 2

my engine runs too hot and i cant figure it out, it is broken in and has good top end, a little slugish in the md range but i cant tell is it because of the temp or not. its running 235-250 degrees in 50 degree weather. when the tepm hits the 90's my motor will be toast if i cant get the carb right, its idles fine and runs good. just too hot. can i get some starting points on all the needles, (my mid range needle is kinda hard to turn).
