If you are getting a good Blue Spark and the plug is not wet than the carb is fouled . As Gator advised using a fuel conditioner / cleaner prior to draining the unit usually reduces the potential for gum or varnish build up within the carb during storage . This fouling is extremely increased when Ethanol fuel is used . Get some carb cleaner (concentrated) and mix up new fuel with 2 ounces of cleaner and let the blend sit for 20 minutes or so . Then attempt to start the unit , you may need to use carb cleaner sprayed into the spark plug hole or carb venturi to prime the engine for initial starting . Keep the engine running with choke or purge bulb to allow the fuel cleaner to begin to remove the build up of gum and varnish etc. Usually cleans up within 20- 30 minute run time .
