Model J175PLEES, can't read serial number sorry, starts fine when cold, when I make a run 10 to 15 mins. stop and start fishing lets say after 15 to 30 mins or so when I try to start it back up it will start and die, start and die. If I keep it in neutral and rev it up it will clean itself out and once I get it in gear and back up on pad it runs fine. I changed spark plugs, still does the same thing. I did notice the last time it happened on Friday, I got up and went back to check the squeeze bulb and it wasn't hard and I had to pump it back up but it still acted up until i reved it back up to clean it out. I just bought it a month ago and it hadn't been started since last Aug before I took it out. I've had it out 3 times already. Like I said it runs fine once it gets going and up on pad??
