Carb floods

I have a Ford 2000 - 4 cylinder gas, marval scheblier carb. When I mow my side ditch if the engine is leaning to the left ( carb side high ) it runs fine but if I mow engine leaning left ( carb low ) it begins to flood out. I have tried different mixture settings but no real difference. Would anyone have an idea on this?
 
Float may shift to the side a bit and rub the side of the float bowl so it causes it to hang up. Time to maybe open it up and adjust the float so it cannot hit the side of the bowl
 
Also does that carb have a vent hole comming from the float chamber.
Could be pouring out of the hole. Some of the carbs I have worked on
have a little tiny coiled spring that goes on the float pivot pin, to
hold the float ever so slightly up pressure. Keeps the float from
jumping up and down thus the float gets too low and floods out. It is
used on carbs fror tractors in bumpy fields. Very sensitive little
spring.
 
The float has 2 "pontoons",one on each side.

If you go into the carb, give the float the "shake test", listen and feel for fuel in one of the pontoons. If one side has leaked, it will tend to raise the fuel level when that side of the float is on the down hill side.

Those are simple and popular carbs, easy to fix, parts available.
 
This may sound stupid but I had a Massey 35 that would run just fine bush hogging going 1 direction on a hillside and would flood out going the other way. Pistons and rings were so worn out that the cylinders couldn't draw the fuel in. It ran fine till it finally just quit and I did a compression test and found low compression & did a rebuild on it. Just something you might want to do (compression check) Keith
