Some 55 years ago I learned the basics on an Aircoupe with Continental C90. From the outset students were instructed to use carb heat at all times except for takeoff and initial climb. When the throttle came back, so did the carb heat knob. The instruction followed several frights caused in all seasons, culminating in a well executed forced landing from which the aircraft was flown out. I never encountered another aircraft so prone to carb icing, it certainly was not as bad in the Piper Cub C90 installation.
As a licensed engineer I was able to monitor the Aircoupes for many years. The engines were unaffected by the procedure and remained very reliable until the a/c reached end of service. I know not the first thing about the machinery mentioned, but sometimes old remedies still work.
