17.5 B&S cyl fills with raw gas

17.5 B&S cyl fills with gas if the choke gets closed for starting... I mean it fills the cylinder and the engine won't turn over... If I remove the plug and turn it over a few times at 0 throttle it all sprays out... Put the plug and restart mower at low throttle and it will start and run pretty good for about 5 or 10 minutes, then it starts missing, like it's flooded... I'M TOTALLY PUZZLED BY THIS ONE AND WOULD APPRECIATE ANYTHING THAT MIGHT HELP!!! It's my wife's little mower and she gets all upset, when her baby quits. Especially when the grass is still growing as fast as the weeds... Thanks... Tom

I would check to see if the float in the carburetor is stuck open.
I'll see if I can find any info on how to check the float for sticking,,, Carbs are not my specialty... I do valve adjustments, some electrical and normal maintenance... Any hints would be appreciated... Tom

If you write down the model number, you can type it in on Briggs' website and download the service manual which will have exploded views and breakdowns of everything.
