High idle

Hi new guy here, I’m having issues with carb it won’t kick down the idle by way of the peddle but I can do it by hand. It was running good yesterday. Here a picture of the carb and what I press to get it to idle at normal rpms.. this is my first forum I’ve ever been apart of so sorry if I’m in the wrong place to ask this..9556DAF1-248E-43D1-92CA-2BF18D421549.jpegBF0E1E10-268A-488F-8697-6B8EA8541FE5.jpeg
