Hi im new to the forum. I have an 02 trailblazer 250 2 stroke, it has sat for several years. I got it going again and it rode fine. I let it sit for another month due to work and now when I ride it will ride fine has plenty of power, but as soon a I hit the slightest puddle it boggs out to the point where it wont even move under its own power. I can sometimes put it in neutral and rev it up then when I put it back in gear it will go, sometimes it wont rev at all. Ill put it back on the trailer and when I go to pull it off, it runs fine again. I have cleaned the carb/jets out several times. I have been changing out the plug almost every time I ride it. The plug will be really blacky almost greasy looking and sometimes soaked in gas. I took it to my local mechanic and he said when he turned the fuel to reserve it ran without any problems. He thought the fuel system may have been clogged. I take it to the trails and the first puddle I hit, it happens again. Srry for the long text but Im just out of ideas. Could the carb need a rebuild kit? Could I be sucking water in from somewhere. Thanks in advance
