Welcome to my way of thinking about Crapinese, Chinesium, junky, Z series spark plugs...lol...The FIRST thing I ever do is throw that sucker away as useless and try to convince others to do the same...It still totally amazes me just how many problems people think they are having with their motors when many times, it is nothing more than those crap, Z series spark plugs that come with these Chinese kit motors...lol.The NGK br6hs works like magic. All I did was change the plug and it's running great. Could hardly even get it started with the crap chinese plug
