My son was mowing lawn for me when I realized the mower didn't sound right. I wnet to check it out. He had been mowing with the choke on for about 15 minutes. Now the tractor back fires and doesn't runn smoothly with the throttle all the way open. The mower is a Husquavarna 2148 21hp 48 in deck. What damage could have been done to cause this result. thanks
