At what point do you open that little flap that pulls combustion air from the cylinder area for a preheat? I've never bothered with it.

When the carb gets choked with ice?

Hi,
it does in Germany! Most, if not all of the G models here only have heated handles -> no carb heaters...
Same story with Stihl so it must be a German thing.

Hi,
yep got the blue plastic cover and the plug thing.
It would be even better if I could actually use them as intended. They are made for the "slotted" starter cord cover but the cover on my saw is one with square holes instead of slots. I was able to modify the blue cover to fit but to be able to use the plug I would have to modify the starter cover too...
Quite annoying as I usually only cut things in winter.

I never use the winter kit ,,,
been cutting in -15 celsius with no problems ,,,,
talked to my dealer about it yesterday, his advice was to use the kit if you experience trouble only ,,,
though I never asked if there was any danger in not using it ,,,,,,,,

Yep... And it doesn't have to be even close to freezing to get carb icing...
Thanks... I'm sure it's in the Owner's Manual somewhere, but my dealer lost the one that came with mine, and I threw away the one he printed out for me in a fit of desk cleaning.
Anyone have it in a PDF?
thanks,
Ian
Edit: Nevermind... seems that Owner's Manuals are indeed available at the Stihl site.

cold weather
cold wheather sucks to work in
i have used foil tape too help reflect extra heat back to the carb on my logging 262 husky west coast special

carb icing
I'm out of left field on this, but if I recall (this is many beers and years ago) I took a 'ground school' class in aircraft training. Details are too boring.
I do remember something about "carb icing" as most (if not all) smaller airplanes in the 'states have carbs and carb heaters. Carb icing was most likely to occur in temperatures just above freezing (3- 5 c) due to the high relative humidity of the melting snow and such. Your best bet to avoid carb icing would be to avoid cutting in that range, at least w/out the baffle (stihl here) turned to the snowflake side. Needless to say, Ky prolly won't have much a problem with this.

It can occur much higher and lower than that.
From the web...
Carb icing occurs when there is humid air, and the temperature drop in the venturi causes the water vapour to freeze. The ice will form on the surfaces of the carburetor throat, further restricting it. This may increase the venturi effect initially, but eventually restricts airflow, perhaps even causing a complete blockage of the carburetor. Icing may also cause jamming of the mechanical parts of the carburetor, such as the throttle butterfly valve.
The following chart if about aircraft, but applies to most small engines. Note that power changes the likelyhood of carb icing
