I have a 1990 big bear 350. It just started dying and back firing while being rode. Also tries to die out while riding. If I down shift then shift back up it runs ok for a few minutes. I've read a few things that the fuel could be to lean and needs adjusted. My buddy said timing chain. Any help would be appreciated thank you
