Back story... bought my tree five seven new 2010. Cut 7-10 cord per season and ever since new I always felt the oiler was stingy. With it turned up to the max and the bar oil holes slightly enlarged I always used about 1/2 tank of oil per tank of gas. Well after a little research and some help, I decided to try a mod.
With the oil pump removed, push up on the adjustment screw and remove the pin.
This will allow you to remove the piston. Here's a pic of the pump apart.
The angled end on this piston creates stroke as it is turned by the worm gear.
Idea here is to show the starting angle, then increase it a bit to create more stroke. I did that with some emory and a flat surface.
