This.
On some engine installations, to ensure better engine response
and to permit a go-around to be initiated without delay, it may be recommended
that the carb hot air be returned to COLD at about 200/300 ft on finals.’
I'm on a PA28-140 with push throttle, not quadrant style.
The carb heat is directly under my thumb with hand on throttle.
Go around and touch n go with hot air is very noticeable in terms of power reduction.
Thank you to all contributors.
Interesting AAIB report...
