Hi guys.

Can anyone explain me what carb icing is? I thought I knew it, but reading an article in BiKE (brit mag) I realised maybe it wasn't exactly what I thought it was... [:I]

Carb icing is ice accumulating inside the venturi of the carburator. It usually happens at temperatures slightly above freezing during high humidity. It is caused by the refrigeration effect of the air passing through the venturi and creating a low pressure area. The temperature drop is enough to cause moisture to condense out of the air and stick as ice in the carb.

I see... and... would that happen in a rainy, 15 ºC (57 ºF) day on my '02 636? I mean... how can I know it is happening? In BiKE they say it feels like the bike is running out of gas... Well, sometimes I feel something "funny" with the bike, just like running out of gas. Could it be carb icing, or is it my head playing tricks (is known to happen ;))?

I've been riding most of this winter and some mornings have been in the mid 30's to low 40's. I haven't experienced anything odd like carb icing on my 2000.

I'll check the fuel filter on the next service. I too think it's not carb-icing...

Maybe it's me [:eek:)]
