Hello everyone my hummer chinese atv wont idle, dies when you throttle and air blows out of the carb. I've tried to fix this crap for 5 month or more, there is spark, conpression and fuel goes to carb that is new i've adjusted the carbs screws like 300 times. It sometimes starts but like in 3 rd try and sometimes dies instantly, sometimes blows air out of carb or sometimes idles and after like 2 min dies, if i press throatle dies instantly. I realy dont f ing know what to do.
