ok i have a 24 hp briggs that i have had for 7 years it only has 400hrs on it..and now it is running rough and backfiring while no load. when you engage the blades the motor smooths out and she cuts like a beast.and as soon as you turn the pto off it goes back to poppin and snortin...i have changed the carb,plugs,filters,oil,fuel and fuel lines and fuel pump..spoke to a guy in town about it he said to adjust the govenor so i did just what he said and low and behold no change..i also set all valves at .05 just like the manual says...so maybe someone here can help me.what could it be?
