I think having fuel in the filter bowl may not mean there is fuel in the carb. In order to eliminate the "no fuel" problem, I would let it sit for the time that you think and then open the top of the carb and see what you have. Don't try to start it. If the fuel is there, you have eliminated that from the list and can move to spark. If it's not there, then you know you have to fill the carb before you start. A plastic bottle with some type of "straw" or plastic tubing would work. Fill it through the brass vent pipe.
Good luck and let us know what you find.
