Winter flying the ERcoupe

Just flew my '48 ERcoupe with the C-85 engine with Stromberg Carb.  Temps at altitude were hovering right near mid-20's.  Any cautions of flying in those temps and the Stromberg Carb?  Having come from 25 years of E-Series Bonanza ownership where Carb icing concerns where pretty much  a non issue I would like to hear from more experienced Coupe flyers of their experiences.  Thanks.
