I recently purchased a 2004 eXmark 36 inch Turf Tracer HP that had a Kawasaki FH430V 15HP engine. At low rpms the engine sounds like it is going to die at higher rpms the engine runs fine. The mecahnics at a local dealership called this "loping." They first suggested that I take off the carborator bowl and clean out any debries. I did that but the problem continued. The dealer mechanic then said that there is a jet on the top of the carborator that needed cleaned. I took the carborator off but could not find and jet to clean. Can anyone advise where to find this jet to clean?
