Johnson PO-15 compression release

[Buccaneer]

I thought I read in the Johnson 3rd Edition manual (digital) on how
to adjust the compression release, but can’t find it (if it was in there)
an for some reason that pdf file is not "searchable" for me.
The compression release lever moves an adjustable rod
that turns the vane in the fuel port.
I presume the vane should be fully closed in normal operating position.
The vane seems to rotate 360 degrees (with the control rod detached)
so I don’t know exactly where "closed" is.
I didn’t think to mark it somehow when I had the cylinder off.
Any ideas on the adjustment procedure?
Thanks!

Of course the lever on the By pass port operates through a 45 degree range. In the run position it is wide open, in start it closes the bypass so the full charge goes to the starboard cylinder. At the same time it depresses the compression release making the outboard easier to crank. I have never worked on one but feel the handle should move 22.5 degrees on either side of pointing straight out from the cylinder. With this assumption it should engage the compression release valve at a little over 20 degrees to the port side. If you have one of those long goose neck cameras that fit through the spark plug hole, you may be able to check on the bypass opening with the piston at bottom dead center. . . ❓

Thanks for the reply Gary. The test barrel is put away until about May,
otherwise I’d see if it runs, then play with the port vane and see
where it "sounds right".
Another reason I should have one of those goose neck cameras!

I saw one on sale on black Friday at half the price I paid for mine (Supposedly also on sale). . . 😥
