- Well, when I was at the Robinson factory CFI course, a guy from Alaska
- asked Frank Robinson about that - seems they get something called ice
- fog when it's really cold. Frank's from Southern California and couldn't

- guy clearly seemed to think that carb heat would make things worse.

- I'm just guessing, but maybe if you have ice crystals which would normally
- stay suspended in the air and get sucked right into the cylinders, heating
- them until they are liquid might allow them to refreeze in places you'd
- rather they didn't. Perhaps one of the bush pilots can say for sure...
