87 Trx 250 wont idle down

I recently started working on this four wheeler about a month ago the engine starts fine and idles fine at first but when it warms up it slowly starts revving up. I have taken the carb off and cleaned it thoroughly and it still revs up. If anybody has an idea I'm all ears. Thanks.

Check your cable. My wifes 300 would do the same thing and it was the fuel cable being too tight at the handlebars and also check the adjustment on the carb make sure its not screwed in too far also.
Thanks I'll check both of those.
