I used one of the new gaskets on what I call flatside oil pump [see pic], well after adjusting the slotted oil adjuster a full 9 turns from bottomed out. I am not getting any oil feed to the primary, all passages are free. Anyone else have the same dilemma.

There are two types of flathead pump gaskets. Look at the oil ports in the pump gasket surface verses the holes in the gasket.

Upon reflection, i was informed by a good source, that the new gaskets where superior, but alas not the case. Thank you for the replies to all.
