    Hey Guys, I've got a CV22 kohler on a scag rider and it runs fine except for this problem. The mower fires right up when it is not warmed up. After the first lawn and I go to start it again when it is warm, it cranks for 3 or 4 seconds before it barely sputters over to a normal RPM. What can cause this problem? Thanks

    Possibly bouncing on your trailer from one account to another with the fuel on is causing a flooding problem ? Are you choking it when its warm ?

    Check the fire on your plugs when the engine is cold. Then when it gets hot and does not want to restart check the fire on the plugs then. The coils or SAM unit (if it has one) could be getting weak when it gets hot. Also try putting a fuel cut off on it because it could be the "bouncing on your trailer from one account to another with the fuel on is causing a flooding problem" as restrorob
