is it possible that 5% fuel can run better and cooler than 20%. i brouhgt some 5% fuel the other day and it seem to make my buggie run a little better.(the motor is just about had it) when i was runnin 20% it would bog down when it got hot and almost come to stop

You have to adjust your tuning for each type of fuel. 20% will get more power and run cooler as the engine has less work to do.
