Kawisaki 25 hard to start after warmed up

[ArTurf]

My '08 kaw starts up fine when it is cold but after it has ran and you try to start it on the next yard it is very hard to get started. It acts like it is not getting enough gas. I will choke it briefly to get it going but if you stay on the choke too much it will flood. Sometimes it backfires like there is too much unburned fuel in the exhaust. I have adjusted the valves recently so I do not think that is it. If it is the carb is this one difficult to work on?

Check the inside of your spark plug boots for rust/corroded connectors, The boots stand straight up and water can enter around the wire. Rust/corrosion can cause a bad connection and weak spark intermittently.......
