my sons 2001 sportsman is in need of a new carb. I am looking for one that will work with it. I don’t like the electronic choke or the oil injection. I bought one from eBay and I will never do that again, huge piece of junk. So the factory carb is an mikuni am7 it’s a 19mm carb I believe polaris only part. In 03 I think it was switched to a mikuni vm16. So which brand name carb would work? I’ve seen some for sale at reasonable prices but I’m no expert by any stretch of the imagination so I would really like some help.
