    Was cutting up branches and bucking today . 30 deg. and snowing, saws started acting up,pulled air cleaner cover seen carb covered in frost. Ms 180 for the branches ,Had the worst icing with the wt 215 carb.
    No shutter for air box heating. 362 M-tron started acting up ,took a look at the carb it was all frostie then I moved the shutter to winter mode then it behaved.
    first time I ever had this happen.

    You dont know "icing" until you're at 3000 ft in a Cessna 150 over water and you start pulling your carb heat...and hear the engine shake and shutter...then pop.....and clear out.... yup....you start to get very religious fast.

    If you got enough humidity in the air it can happen at above freezing temperatures. We use some air mixers at work and the mufflers on them will freeze up after 20 mins. It's never below 85 in that building.

    I've heard of icing on the cake but not icing on the carb,...

    Two thang, get ethanol free, close you winter shutter, run a Stihl they are factory hot. OK that's three but you homos can't spell or count so two outta three ain't bad...
