jeff,

They used to preach a 20/20 rule flight school. That is, if temp and dew point (I think dew point is about the same number as % humidity at the ranges we're in here in Indiana now) are within 20 of one another, watch out for icing. It's a lot more dangerous in the air, as airplanes don't make good plows.

But it's none the less frustrating on the grond here in this wet snow we've been having lately. Like guys have been saying, the gas mixture can help a lot. But sometimes even that doesn't work -- and we've been having that kind of weather here lately. So in an airplane, there's a trick called carb heat -- which is basically just a flap that lets you duct heat from the exhaust manifold around the carb. The big downside is carb heating robs a heckova lot of power.

Short of fabricating a whole sheet metal ducting system for what's a month - three month problem here, a cheap and dirty trick is radiator hose clamps and tin foil can move a lot of heat down to the carb with a intake/exhaust combination like my H. If the 406 is a cross flow, the whole thing has to grow a lot. Anyway, that approach doesn't cost a lot, and along with the right fuel blends, should fix the problem.
