I'm in need of some help. I have a '97 Big Bear that I've never had a bit of trouble with. Now all of a sudden it started making a burping sound through the carberator or the exhaust. I cleaned the carb. and this seemed to correct the issue for awhile but it started doing it again and now it won't start. Does not seem to be getting fuel. So if someone could give some help I'd really appreciate it.
