Engine shut off when turning right

Got a sears suburban GT/16 not sure of model number. Engine is a onan twin. Runs good on flat ground or turning left. But when I make a sharp right turn or if on a hill side leaning to left engine will shut off or start to sputter.

OK I WILL JUMP IN HERE AND TAKE A GUESS AS TO WHAT THE PROBLEM IS WITH TH ENGINE SPUTTERING & SHUTTING OF, OK FIRST I THINK YOU HAVE A FUEL PROBLEM, NO THE LACK OF FUEL PROBLEM. THE CARB. MAIN JET PICKUP IS ON THE RIGHT SIDE OF THE FUEL BOWL. FOR SOME REASON YOU ARE RUNNING A VERY LOW FUEL LEVEL IN THE CARB. WHEN TURNING RIGHT OR LEANING TO THE LEFT THE FUEL GETS AWAY FROM THE PICKUP HOLE. HAD THAT IN ROUND TRACK CAR RACING YEARS AGO. GOOD LUCK JIMMY

If you have some secret switches or any other kind of thing in your truck than i think it is the problem of that thing because whenever you turn right the switch presses and your engine stops.

Thanks alot for help . What I found out after checking that the float needed adjusting. Now it funs fine.
