On my newly acquired old Poulan S25DA. Didn't run when I got it. Replaced the crumbling fuel line and rebuilt the carburetor and now it runs fine. Problem is that when I rev it up oil is flung out down the bar. I mean a streak in the floor. Is there a way to adjust the bar oil flow? It uses more oil than a Mazda RX7. I took the oiler system apart but nothing looked amiss or broken
