I've been so happy with my mower. Hustler with a 25 horse Kawasaki. Has just north of 300 hrs on it. Last week, it started (first start in morn) cut off, and I had troubles getting it going again. It appeared to be flooded. I got it going and it would not start on my first job (didn't even get it off the trailer). I can see fuel sitting in the air intake housing just outside of the carb. If I get this fuel out and drain the float and run it and run it and run it SOMETIMES it starts and SOMETIMES it stays running long enough for me to keep it going. The other day I did all my jobs without turning the mower off until the last job. What a headache. New plugs. Meticulous maintenance. The only thing is the valves, but its just got over 300 hours. I took the carb off and cleaned it twice! Afterwards it would run fine, but after a cool off from hot, it would flood again. Float seemed to be working fine. Today it backfired after turning it over and over for 15 seconds and trying it with start fluid. This is getting ridiculous. Any suggestions/diagnosis? matthew BY the way, when I pull the plugs, they don't look wet???
