Good old chainsaws wanted

The Poulan 4000 has an automatic oiler. It does have a manual oiler as well for additional oil in certain applications but it wasn't intended to do all the oiling. Perhaps the auto portion of your oiler wasn't working?

I do not recall seeing an auto oiler on the 4000, but it may have had a diaphragm auto oiler that
was not working well. It did not have a worm-drive auto-oiler like modern saws have; I
would have remembered that.

The S25 above has a dual oiler (auto + manual) and the auto-oiler was definitely weak,
due to a stiff old diaphragm. That part is not available any more, so the manual oiler is all you
have. I have other old saws with weak auto-oilers and no manual backup. These also
used diaphragms and the needed part is not available.
