Make sure there are no fuel leaks throughout the system. There does seem to be fuel in the spin on filter, many will fill it with fuel before installing it, I do. In my case I pump the primary filter maybe twice, fires right up.
Also make sure the primer pump handle is tightened down, just turn it clockwise, when it's in the down position, as in tightening anything else. New style pumps are just a button, no locking or unlocking required.
