after cutting yard for 30-40 minutes, and parking the lawnmower in garage, 20-30 minutes after this gas will start coming out what looks to be a discharge hose, trying to figure out what is causing this?
If your engine has a fuel cut-off valve make sure it's off when not in use. Check engine oil dipstick for being over full & smelling like gas, if so let us know.
If your mower is in garage with vehicles & gas or electric water heater raise garage doors & remove mower to outside away from house ASAP.
Fuel shut off valve is under front of fuel tank page 24 your operators manual.
