Hey, I'm 16, and I just purchased a used 1997 MXZ440F with 930 miles,(yes, 930). I pulled it out of the guys heated garage, started in 3 pulls, and test drove it. It ran great, no problems in acceleration or anything. I purchased it, and put it in my trailer uncovered and drove an hour to my house. I got home and started the sled while using the choke. It fired right up and idled nice. I slowly accelerated about 30ft and it bogged down and died. I restarted and moved another 30ft, it bogged, but I kept it running. After about 3 or 4 minutes of this I just parked it. It was about 7 degrees out. Is this just the result of the sled being cold or a more serious problem? What should I do, I dont know anything about snowmobiles!!!
