I have a poliars ATV 330 and am unsure what year it is, it is either a 1985 or a 1988. How do I tell the difference?
   It ran fine this past summer and sat for the winter with gas in it and how it will not start. It turns over fine, what should I look at first as a possable problem? Where can I get a service manual for this model and year of ATV.  

start by checking the sparkplug and spark. then check and make sure you are getting fuel to the carb. and if you didnt put fuel stabilizer in, then your carb might need to be cleaned out from sitting all winter. start there.
