Going into my 2nd witer winter the 240. Last year anything under 40 degrees and it would not even think about starting unless I used the TS. Even then it was like pulling teeth. This year It'll start like a champ as low as 30 so far. I haven't even filled the TS reservoir yet. I'll just wind it up till the oil light goes off, let go of the decompression lever and off she goes, banging on one cylinder for a sec then purring like a yammer hammer should. Haven't done anything different other than I haven't been using Power Service in the fuel lately. Not complaining by any means, just thought it odd.
