everything is right, when i went out is was 5 degrees it ran decent would pull 8500, the next day it was 35 ran like crap 7500 rpm. it almost act like the timing is being retarded.

well the warmer it get's power goes down,,they run richer to a point as the temp goes up...

How dialed is the jetting? The change in temperature will make it run richer the second day. If it was already running fat, the higher temp could have made it perform the way you describe. I would do plug checks for jetting for a start.
