I have a Gravely ZT HD 52 with a Kawasaki FR691 and having some issues at low IDIL. My model of zero turn is 991083. It randomly acts like it wants to stall , but when throttle is up no issues. New fuel filter, spark plugs, air filter, gas cap and oil changed 15 hours ago, fresh gas and still having issues. I pulled off gas line going to carb and gas is coming out quick and I didn’t see any clogs in gas line. I put a video below of how it acts. Did it twice in video, thanks so much for your help and support!
