New XT1 46" - warm start up?

[fuzzyducky]

Hi everyone,

I just picked up a brand new 46" XT1 (22hp v-twin Kohler 7000 engine) from the local big box store and I noticed something I thought was odd, so I wanted to get some input...

I started it up for the first time and ran it for a bit, enough for the engine to get warm. I turned it off, and when I tried re-starting with the throttle at low to mid, it would just crank and not fire. It wasn't until I put it in choke that it would start. The behavior was the same even after I finished mowing - it only re-starts when choked, even on a warm engine.

Is this normal? It obviously isn't a huge deal now, but I am worried of headaches down the line, and am wondering if I should exchange it.

If it would help I could probably make a video.

Thanks in advance...

They have engines running so lean now for emissions reasons, it doesn't surprise me it won't start without the choke on. If it has an adjustable carb, tune on it.

I've got an XT1 with 42" deck and 18hp engine. Once warmed up it will start at any throttle position. As Jonathon said it may need some tweaking.
