I've got a 16hp briggs go devil LT... I hunted saturday morning and on the way out to the blind i noticed white smoke coming out of the muffler and the engine sputtering...

I took the air cleaner off today and there was gas/oil spitting up through the carb... The white smoke issue stopped but the engine is still sputtering... There is gas still coming out of the carb when it sputters and i cannot keep the engine at idle as it dies...

Any help would be appreciated... Thanks fellas
