Super two burning bar oil

[super2owner]

hi everyone, new to this forum, but not new to homelites, I have a super 2 that I’ve been working on and it has the diaphragm oiler and it pumps oil to the bar very well but also seems to be burning some, I can’t seem to figure out the problem kind of confused why this system would do this, I know I have the lines hooked up the right way. any help will be greatly appreciated, thanks

Most likely either the lines are reversed, or the duckbill in oil tank is bad, see this post, w/pics houseofhomelite.proboards.com/thread/12119/xl-smokes
