Check the pick straw in the gas tank. do you get the right carb for the motor? Get the code,type, serial number off the engine. Can you adjust the carb or is it a seal unit? check to see if the fuel filter is clogged. check and see if the jets are cleaned out. clean around the inside of the fuel bowl. Briggs is bad about clogging around the fuel bowl area. clean out the gas tank. if these don't work leave message i will think of more later.

It is the right carb, I checked the pick straw, I know the carb is getting fuel, because when I loosen the bowl screw gas comes out.

Does it have a main jet adjustment screw on the bottom of the carb. If so it may not be adjusted correctly.

If spraying ether makes it fire then it stalls you are not getting fuel into the combustion chamber. Just because fuel is in the bowl does not mean it is getting into the engine. The jets may be clogged. You may also have a bad vaccuum leak. Maybe the carb and or intake manifold is leaking where they fasten to the motor. Spray ether around these places and see if it fires. Possibly the fuel may not be up to snuff. Did it run before the repair?

does it have an ajustable main jet or not. if it does open it up a turn or so to get it to run then adjust it. if it doesn't and has a fixed main jet it or the passage from it to the venturi is plugged. The later is unlikely if not impossible unless the carb you bought is not brand new but very possible if it has been used even slightly and stored with fuel, even a little, in it. Was the carb brand new? In any case the problem is in the main jet fuel circuit in the carb. Any engine that runs on starting fluid but dies in its absence has carb troubles.
