Sat my Port motor shut off while running. After inspecting it and letting it cool down. It started right up. But when I got it up to 4000rpm it would drop down to 13 then up to 23 and so one. It felt like it was misfiring but the plugs were in good shape. So I called Dewey's and I will take it in on 10 of Aug. Chad thinks he knows what it might be so that is good. And he says if it is it's a quick fix. lets hope whatever it is it's covered under warranty!!!
