where is the pressure regulator?

 

Ok, looking at the flywheel, behind & just to the right & down of top center of the shroud, there is a bolt on top of the block. (red arrow in pic) This has a spring & plunger under it.  That is the regulator.  Non adjustable, but you can swap for a slightly longer bolt to increase pressure against the spring.  1/8" longer usually makes for enough increase.
