I have a Husqvarna ZTR with a Kawasaki FH531V AS05. Crank it cold and it runs great for the first 10 minutes. After that, it starts sputtering when I put it under a load by thrusting forward quickly on the handles.
The warmer it gets, the more it sputters when moving forward till I'm just crawling while trying to cut grass. If I stop the forward motion but leave the PTO engaged, it will catch back up and run okay. It is only under a load that it acts up. Doesn't take much of a load...
FH531V runs rough under load after 10 min
