It was running fine, and then it started losing power and died. I could not get it to start again. I rebuilt the carb, but now it seems to be blowing air out of the car instead of sucking it in. I got it to fir once but it was more of a backfire. Any help would be very appreciated. I miss my ATV ,I do a lot of work on my ranch with it and it is just not as fun with the small tractor as with the ATV!
