Guess ya don't work on old tractors alot then huh?

Since I've been tinkering with tractors, I've found that discussions on how 
to prime oil pumps on old tractors are just about as common as any other 
question.. so it seems that the issue has been around.  Most of the issues 
I've seen are with light multi-weight oils and worn pumps.. or pumps that 
use a pickup tube that has a leak...  Or if  a unit has set up for an 
extended time and the owner simply wants the first pump strokes to be 
producing oil, rather than running around dry self priming for a few 
strokes.. etc.
That's my take anyway..
