Briggs sputtering when warmed up

[Ezpz]

Just put everything back together on my LT-1000 and I mean everything! I'll start it up (17.5hp 31c707) engage the blades, cut the entire yard and things sound really good. As soon as I stop the blades I hear the engine sputter a bit and it idles like ****. Any suggestions?

You should have a low speed setting screw coming out at a angle near the top of the bowl..... Not the Idle screw way on top....

If I remember right you have a Nikki carb on there..... Most of the ones I have worked on had a low speed adjustment screw.

Let us know Mon Ami ~!~!

Sadly the idle mixture screw doesnt help much. Not sure why it would run great after a cold start and with the blades engaged but then sputter after its warmed up

Do you have that plastic piece on that low speed screw ??

No its long gone. I'm sure there is a pile of them in the garage somewhere
