I have a 1995 polaris 300 4x4 that has been sitting for a long time but its still in like mint condition, i went to start it and that was a job and a half but once i finally got it started white smoke poured from the exhaust. a friend told me that this was because of water in the carb. is this true? what can i do to stop this? my quad stalls everytime i get it running and i think its cuz of this problem. please help
