Hey Gang, first time Forum user so I hope I do it right. Found this Forum when I was checking the net about my new MM-B212. Just got it last week from Rural King for my two grandsons, who love it. However it seems to sputter a lot so I tried to call and email the company with zero response. Starting to get concerned so I went looking and found you guys. COO says it was built Dec 3, 2018 at Ruston and can't find anything about a recall except from you all. I guess so long as it is running (even rough) I'm OK. If you all find out anything else, please post it....and thanks.
