carb ice experience

I got carb ice almost every time I flew the cub. On cold 6am flights,
the Cub just loved to suck up the ice. I learned to leave the carb heat
in during touch-n-go operations until climbing out because I lost the
engine once after shutting off the carb ice as I was moving the
throttle forward. The engine ran far enough to get me 300 feet up then
started to die. Luckily, turning around at 300 feet is very easy in a
Cub, not so easy in a Mooney. I kept a timer for cruise and ran 15
minutes heat off then 15 minutes heat on. I would also often get ice in
the time it takes to taxi to runup. I learned to clear out with heat
first. For some reason, the cub got ice much more than the Aeronca with
the same engine, I think it has something to do with how heat moves
around in the cowl.
