BPF - Oops, got to be careful not to mislead you. I used that checklist as a basis for style not content. It's the format I use. The content on mine is pure Cessna POH for my aircraft normal and emergency procedures with some additions for the toys I have on board.
1. I didn't understand the gauges item either. My list has a dip check in the walkaround and a check of what the EDM700 thinks is in the tank.
2. Carb heat - I also check carb heat on runup. Essential I agree.
3. Don't disagree with Skyhawk on the parrot checklisting concerns either. One should never the disengage the brain!
