97% of the time that is the result of a float valve that has not sealed and has allowed the carb to empty the entire contents of the fuel tank into the intake, which some will go into the cylinder and past the rings, but most will drain down the breather tube into the engine block. Will require removing and cleaning the carb and replacing the float valve with a repair kit. Draining the crankcase and refilling with fresh oil, which in some cases will need to be changed a second time.
A needle is needed on the float inside the carburetor. That or the float is heavy with fuel inside of it. After that the oil will need to be drained and left to sit for a few hours to evaporate all the fuel possible inside of the crankcase.
While you are at it, I recommend a manual fuel cutoff valve midway in the fuel line to the carburetor. Use that to prevent future issues. Ethanol fuel is hard on small engine carburetors, so use non-ethanol of you can get it in your area.
with respect to you and others that answer people that don't give a response to the help that you gave them to let you know you were right, got it fixed, running ok, I do not have a lot of respect for them, I call them "I want what I want" or is it just to Lazy to type an answer.
Out of due respect for the person that answereds the post and got it right it would be nice to thank them. I have answered post and got it right and know I got it right becaused no one els posted anything. Just my two cents. Another thing tnat gets me is someone that post the mower and say they have a certain mower and won't post the real model no. or the engine and not post the model type and code.
