The black goo in the carburetor used to be the duckbill check valve for the WalBro/McCulloch BDC Carburetors.
Some had luck using the Tillotson Carburetor check valve by bushing it in the cavity with a thin nylon/plastic shim.
Done right and installed the correct direction will last way longer than the original and is Alcohol friendly.
