I would have thought for an aircraft, it would be more useful for heating/warming the fuel pump/fuel, since I thought at altitude, temps dropped, especially in inclement weather, and a carb freezing up would be bad. What do I know? realcrazy [/quote]
The newer (1940 and later maybe)Lycoming aircraft engines, both 4 and 6 cylinders, have the carb. mounted on the bottom of the oil pan with the intake runners running through the oil pan also, usually no problems with carb. ice when warmed up.
I did run into carb. ice once or twice in my 15 yrs. of flying Lycoming powered small aircraft, usually around 8500 Ft or higher in high humid air that was well above freezing OAT shock shruggy
The other major brand, Continental, has the carbs. mounted and separated away from the oil pan and they do get carb. ice a lot easier and a lot more often down
