It appears that the engine floods when you apply the throttle, thus why it bogs down, and the leakage from the bottom of the carburetor. Inspect the air filter to ensure it is not clogged or dirty. If the problem is not there, inspect the spark plug and clean or replace it if necessary. If the problem persists, then the carburetor settings are probably too rich. If that is the case, rotate the needle valve clockwise 1/8 turn to close slightly.
If a car starts and then dies, it is possible that poor quality gasoline is being used. Another problem may be that the engine needs new spark plugs.
