If it kicks with the starting fluid, you have answered your own question. It's a fuel problem. It is very likely that when it sat for those few months, that condensation collected inside the tank. Whenever I used to store mine, I would fill the tank plumb full in order to keep condensation from collecting, plus I put in a bottle of "Sta-Bil." After you drain a few gallons out the bottom of the tank, add some stuff from the parts house designed to get rid of water in your tank, then add fresh gas. Take the line loose from the carb and get a can or something to catch the gas, and have someone try to start it while you hold the line over the bucket to catch the gas that is still in the line.
