3120 chain oil

[Tree tech]

Hi there, i have posted this before, i still cant get enough oil on my chain! It has an extra oil lever, correct bar and chain combo and drive, all oil paths and holes clear, oil pump is set to full , running a 42inch bar for logging, anyone else using one?

I don't have a good answer. I can only think the oiler is bad. Never ran a 3120, so I have zero knowledge on them.

It might be the tube behind the exhaust. I supply oil to the oiler from the tank. You can remove the exhaust to check. Or maybe the filter is clogged. You have to remove the filter to check that too. Could be one of these when the hand pump is bad too.
