Poulan sand cast oiler overview (cleaning)

These older sandcast Poulans seem to all have the same issues when going through them. 90% of the time I bet they were retired running and just tossed to the shed as newer models came through. Basically it is just cleaning up the old age of gummed up oils and fuel in lines and carburetors. I took a video of an old manual oiler assembly and what usually is the issue with going through them to get them oiling again. This is helpful when going through any manual oiler as basically this how most manual oilers were designed for most chainsaw manufactures.
