This machine has ran great for me until the temp gets below about freezing. Even when it was new I would always have to run the choke about 1/2 way to keep it running in the cold. We have had a pretty cold snap here this week and now I can't even get it to start. It will pop and sputter and cough but it won't straighten out. Thought maybe I fouled a plug running it with the choke on so I checked that and it looks a little dark and moist but I've seen worse. Just thought you guys would be the best place to start. Thanks.
