I had it wrong in the listing. LT250F.

I opened up the top of the carb by removing the black cap retained by four screws. Afterwards I found a spring and it pulled up the slide with the needle. Some parts fell as I was pulling it apart so I am not sure I have it all and now the bike idles high.

From the top down I have the cover, the rubber diaphram, The spring which I think rides on a plastic shoulder piece which rides on the top of the needle. The needle has clip which I did not move, and under the clip is another plastic piece which sits in the bottom of the slide. The slide slips into the carb. Is there anything I am missing?

 

Best way to find out is to get a suzuki parts printout of your carb and compare it to what you got. You can print out one from pretty much any online suzuki parts websight.

 

I found a picture and confirmed I had it corect. My kids had adjusted the throttle setting at the handle bar which caused the high idle.
