Everything you say is right i havent removed it so nobody knows...

But we checked it and in high rpm's with the mechanism wide open and only a tiny little oil ball (dont know how else to describe it) . I will buy one thought and strip it down,chek it, untill it is perfect and then install it cause 3% oil is lots of money...

maybe a good idea is to have the oil pump in situ and add a very small amount of oil in the gas tank.
