We did the rest of the hour without carb heat, to give him a little more power if he needed to do another go-around
This is not the way to do things - if you put the carb heat to cold either as you advance the power or as you pass 200' (or similar point) you have full power anyway, leaving carb heat off the whole time can result in carb. icing - which of course is why we HAVE a carb heat system, and if THAT happens you will definitely NOT get full power.
