Ariens Snow Thrower - not smooth running engine
I bought an Ariens ST8526LE Model # 932105 or better known as the 8.5 HP model. It has a Tecumseh engine. I ran it only twice last year. My question is it normal for this type of engine to have an occasional sputter, it doesn't seem to run smoothly. I replaced the plug (I choose an Autolite this thime over the champion to see if there was a difference) and changed the oil, but it seems to run the same as last season. I was thinking it's not really broken in with less then 2 hours on her. I had a smaller Ariens at first (6 horse?) and it too ran rough so I thought this was normal.
