[David Mayers]

Please I do hope that someone can help, my Stihl 08S has an odd oiler problem, I have taken the tank flushed it out removed the oiler cleaned the oiler galleries, cleaned the oiler, cleaned the oiler pickup , blown the oil tank out with compressed air, it will oil for about 5 minutes when cutting large logs, its fitted with a 21" bar and chain, yesterday I put on a new oiler, same thing it oiled for about 5 minutes of cutting, then it stopped the oil tank is still 80 percent full, hope that someone can help regards thanks David.
