I know the subject has been changed a bit to safety, but I still need some engine help.

My instructor has my engine set rich enough to be blowing a lot of fuel out the muffler. Normal?

Also, I have been flying recently in temps ranging from 28 deg F to 70 deg F in a couple of days. I will have to richen the high speed adjust for colder weather?

From some advice above, I know that I'm already needing to adjust my low speed idle (didn't even know I had one) because of a major hesitation going to full throttle.

Thanks-
