Buzn,on my trucks, the carb icing gives no outward appearance other than moisture condensed on the carb throttle body.If the truck is driven from a cold start for a few miles at 40 mph, the intake heat does it's job , but if I drive a mile then down shift to make a turn,the engine may stall once, maybe,conditions have to just so.After the first stall, never happens again.During cold weather,never happens.I believe gas companies still use a different brew for cold weather that tends to lessen the problem.
Hmm, where I live in NY has no tornados,hurricanes,volcanos, floods fires or quakes,just cold winters.My trucks can live with that
