HI, MY 20 HP B&S EGINE ON MY JOHN DEERE "SURGES" AFTER I START IT AND REMOVE THE CHOKE. IN MOST CASES WILL SHUT DOWN AT LOW THOTTLE OR SURGE . THE FULE FILTER IS NEW, NEW PLUGS, FUEL PUMP IS NEW THIS YEAR. I VERIFIED THAT THE FUEL PUMP IS WORKING. I CLEANED THE FUEL CAP SO VENTING IS NOT THIS ISSUE. I REMOVED THE CARB, CLEANED THE BOWL AND VERIFIED THAT THE FUEL SOLEONOID VALVE WAS WORKING. NOT SURE WHAT ELSE TO LOOK AT.. ANY HELP WOULD BE GREATLY APRTECIATED!!

Most likely either water in the gas, or a plugged main jet.
