Newer 391 in the shop, won't oil

Did the typical. Cleared the oil hole in the bar, pump isn't pumping. Not a Stihl guy. Hoping its a simple fix....

Havent been in one yet. But if like the 290-390 I would be looking at the worm gear metal arm to see if broke or wore in to.  Maybe not even lined up with clutch drum etc.

That seems to be what it was.. good call. I bent it out some as it looked like it didn't engage with the clutch drum... oils now... for how long?

I had a 025 that the metal arm has worn off on the end to where it didn't actually reach out far enough to be turned by the clutch drum.
We should share what we know... someone may learn...
