thanks cup ...mine sits in the garage ..not heated either . lowest temps have been around 6 deg. anyway just got back from riding , decided to choke it to shut it off . it made no difference, the engine ran the same . come to find out , the choke cable had slipped in the clamp on the carb so i was getting no choke at all this whole time . re -adjusted the cable and choke now closes . simple fix . i will know tomorrow when i choke it and fire it up . i think in this cold it still takes a strong battery to crank the starter good . jboy
