Mine has a plastic float and needle with nothing to bend or adjust. A speck of dirt will not bend anything, very little pressure needed to seat the valve. But the manual does show a proper and wrong way to install the spring on the needle valve. One thing you can try is to make sure the float can float, meaning make sure there is no gas inside it. And also take a q-tip and gently clean the seat where the needle goes in. Check the tip of the needle for nicks or imperfections that could keep it from seating and stopping fuel flow.
One more thing to check is the "2" fuel filters plus make sure the fuel lines are not old and brittle inside, they can release little specs of rubber that can mess with the needle valve too. Replace the fuel lines and filters and clean the carb once more and see if that clears it up.
