I have done all of the recommended steps and checks to get the oiler working on my old Poulan XXV. The last step was to install a NOS crankcase check valve. When I rev the saw up with the bar off I can see oil trying to come out of the tube but it does not really flow. I have used a WD40 spray tube and my air compressor (set on low) blowing into the opening in the crankcase leading to the oil reservoir to verify oil will flow and it does. On my saw there is a "feature" which does not show up on the exploded parts lists. It can be seen in this photo I loaded to Photobucket. It appears to be a "bent pin" which can spin freely in it's opening and I can see oil "seeping" out. I am guessing it is some sort of pressure relief mechanism but am hoping someone can clarify it function. If it is letting pressure escape I'd like to seal it up but wanted to check here first. TIA for any tips.
