I got an 06 rancher not too long ago and the weekend before the mud bogs it wouldn’t start. Brought into a shop they cleaned the carb and it fired right up again. Brought it to the mud bogs, didn’t go deep just drove around the edges of the mud holes a little while I drove around the park and watched. My exhaust started to smoke through out the day and at night it was really bad and when I was driving back to my campsite it stalled out and I checked my oil and there wasn’t really any left. I added oil again and it still won’t start, Any ideas why?
