Check for spark. If its got spark than its probably fuel related. If you left gas in it, then it could need a full cleaning (carb, fuel lines, filter, etc). Before you clean the heck out of it you should check the compression and make sure it isn't shot.
The quick easy way to check compression of a chainsaw is to pick your saw up, hold the starter handle then let it hang from the handle. The saw should NOT lower to the ground. If it does then you have lost compression.
Always drain your saw of gas when you plan on storing it. Then run it till its completely dry and has no fuel in at all. Then put it in a dry place.... that's the best way to store them. you can leave the bar oil in it, it doesnt go bad......
