I'm sure I gave it enough time as it went up/down a few times?
I took the pump off the engine, and a load of oil ran out of the pump where worm gear shaft goes into the pump body. Is that normal? There is a gasket there, but is that worm gear cavity supposed to be full of 2T lube?

The height of the pump is determined by the pitch of the throttle. I don't think you gave it enough time to actually depress.

If you think its broken then my advice would be to ditch it and run premix. They are liability anyway.
