Carb funk. It will start eventually, but maybe not before you run the battery down. You can get a charger for cheap that's useful to have anyway in the event you run the battery down. Not sure you really need to leave the petcock on prime or put it in prime for more than a few seconds. What's happened is the gas or additives or something have had a chance to clog up your jets/or some other part of the carb and the cure is to ride a couple of gallons of gas through the carb. All of us have had this problem to some extent. Best cure is to ride regularly, but outside of CA/FL not always possible. Search the threads - this is one of the top five topics on here. If you are gonna put it away for the winter there is a bunch of things you ought to do that are also on here in other threads.
