Maybe it's a stuck float valve or a bad float. Had a similar problem on a TORO rider but that turned out to have a pin hole in the brass float, it filled up with gas and let just about the hole tank through the muffler. I changed the brass float and still running to this day! Note: your float may not be brass if it is a newer machine it will be plastic.

Remove the spark plug and try pulling the starter again. You may have a fuel leakage into the cylinder and it has caused a hydraulic lock. Check/change the needle and seat in the carb as this leaking is the usual cause if this type of problem. Good luck and please rate this solution.

Lawn boy 2 cycle mower won't start


Replace the spark plug and retry.
If a new plug does not work push the spring button on the bottom of the carburetor to make sure fresh fuel is in the fuel bowl.
if this does not work remove the spark plug and squirt some light oil (like wd 40) right into the spark plug hole; roll the engine over slowly a couple times using the starter rope. put the plug back in and snap the plug wire in place. If the mower now starts after a couple pulls it means the rings are worn, replace the rings.

Just bought a 10 year old lawn boy 2 cyl mower from my neighbor. He had not used it for 5 yrs (heart problems). I put the 2 cyl ashless oil into the gas like the instructins said 32/1 mix. That turned out...


Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helps
