Craftsman 24hp briggs runs rough
Hi all, Have gone thru alot of posts similar but this maybe different. YTS4000 tractor has only 14 hours on it. just over one year old out of warranty. Loved the smoothness and power of these motors before, but this ones not right. Always felt a bit off but mostly with blades engaged. It just started running rough with stumbles and backfires at governed engine speed, no different fuel or damage noted. model 445677. Checked valves, changed plugs and fuel filter, solenoid clicks on, fuel flow and cap seem ok, but 14 hours??
