i have 2 Kawasaki fs541v that run great until it gets hot. They have done it since new. I have a brand new demo that is doing the same thing. After using them and loading them on the trailer they are very hard to start after arriving at the next job. I suspect the needle and seat leaks so during transport they are dumping fuel into the engine. They have solenoids to shut off the fuel when not in use. Any body found a solution to this?
