Sears Eager-1 Self Propelled Lawn Mower

My lawnmower runs but very roughly no matter how long I let it warm up. I changed the spark plug, fuel, and air filter. When I lift the front end up about 18 inches or so, it spools up and runs perfectly. But, as soon as I return it to level ground it sputters badly.

You might have water or trash in the bottom of the fuel tank.

Engines Behaving Badly

You didn't tell us WHAT KIND of engine so we'd know what
we're dealing with. It sounds as if the float in the carburetor
is set wrong or something that would be affected by the
angle you put the mower in ?? I would guess that by your
angling the engine by raising it 18" off the ground, you're
leaning it out and making it run better. So...check the float
heighth (especially if this is a Tecumseh) and try setting it
a bit CLOSER towards being level....but NOT level, and let
us know. You can adjust the float heighth by bending the
tang the inlet needle hangs on.

Hello P3NED!

Two good points here! When you remove the float bowl, check for water coming out of the bowl. That and/or the float setting could well be the problem. If you have never messed with the float before, then there is really not any reason it should be in need of adjusting though. Does gas come out of it when it is shut off? Is the air cleaner soaked with gas or clogged with trash?
