"lo torcrida tai gleki se mu'i lo nu cikygau na gi'e sipna stali curmi"
"lu ta'i ma nerkla lo mi'a zdani —sei lo torcrida cu stali retsku li'u"
It seems to me that you are trying to use "stali" in a sense of "to continue to do something". That's not what it means. It means to remain with or at someplace ("he remained home", "The smell of grapes linger on his hands") You are probably more interested in the tense "ca'o" or the gismu "ranji".
