Don't get fixated on one thing when you have a problem. My 066 put together from junk parts was not pumping oil. No problem, I have had this before. Took the line from the oil bag and all looked good. Checked the worm and the pump. Good also. Made sure the tang was engaging the clutch drum, yep. Well as long as I have it apart let's blow some air through the oil passage to the bar. 180 pounds and no flow, clogged tight. Before I got it some tiny bees got into that passage and built a nest that was not going to go away until I drilled it out with a long bit. WOW
