John Deere mower slow to start

The last couple times I used my John Deere JS25 mower (Briggs motor) it started the first pull when it was cold, but once warmed up, it takes about 10 pulls or more and it starts slowly once it does crank. It has always stated on the first pull for me. I replaced the spark plug I think two years ago. Any ideas? Thanks

Does it have a primer, choke, or autochoke?

That's kinda what I figured. These are notorious for that problem and it's design flaw. Normally you could just apply a little choke or prime it a couple times and go. Not these... when the engine is warm, the thermostat holds the choke open. The best work around is to tilt the mower with the carburetor side up before trying to restart. This allows a little gas to enter the throat from the carb bowl and make it easy to start.
