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.
