Jaws, i think the valve is design is all the same principle,
a ball is pressed into a seat and seals the passage. in theory...
I talked to my engine guy and he told me
on flatties you can only try machine the seats,
as the pump housing is cast iron.
the later ones, like shovel e.g.,
are made of aluminium and you can drive the ball against the seat
with tiny hammer strokes to make it sit better.
Obviously not a good idea on the cast iron ones
He told me to keep going and watch it closely, just like all of you,
so what i'll do.
Rusty:
I really had to refill after i got it running,
no oil traces on the dip stick anymore...
