2010 PYT9000 42" mower with B&S engine. Initially it started ok but slowly it got harder and harder to start when cold. I now have to jump it with the car battery and it just cranks and cranks and cranks and eventually it starts but only after about 30 minutes of off and on cranking. The engine only has 25 hours on the timer and it onlty starts with full choke. It never starts without choking. Runs fine and restarts eaisly afterwarmup. Yes, it's got fresh fuel and it's getting spark. Any ideas?
Thanks, Jim
