A few things can cause gas to flood the engine;
Having the petcock on "PRI"
A faulty petcock when in the "ON" position
Stuck float bowls and dirty carbs
Also if the crankcase is flooded with oil and gas, it can be forced back into the airbox will the engine is running. An overfilled crankcase can lead to damaged engine seals and increased engine pressure that can make the engine hard to run.
Drain all the oil, replace the oil filter, add new oil.
Remove the air filter, clean, relube lightly and replace it.
Remove and check the plugs. If sooty/oily and black, clean or replace them.
Remove the gas line from the carb, if gas flows without the assistance of a vacuum in the "ON" position, then the petcock may be the problem.
