oil pump stroke
should my oil pump increase the stroke when the throttle plate is lowered? it seems to not really change:

The oil pump runs off the gearbox. The higher the rpms the more it pumps.
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.
Yes that's what I thought, but the stroke should still increase at any speed if the pulley is depressed? 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?
