Hi.
Well, I won't say that ALL Cosmos PTO's will give you as much trouble as =
I
had.  Remember, the first PTO I had contained some damaged components
("Springy thingy") and a couple other problems and the 2nd unit had some
other "multiple issues" with it. =20

However, as evidenced by the relative ease I had after overhauling the
second unit I will have to say that if your PTO is otherwise in good
condition you may have little or no problems at all tuning it up. =20

One thing that IS worth noting is that neither of my units needed to =
have a
turn removed from the end point coil though I did that to the first unit =
and
ended up having to rewind the coil with the proper 3 turns.  It appears, =
at
least in the case of these units that cleaning and lubing them seemed to
bring the end points in to where they could be adjusted with the end =
point
coil.

Good luck with your Cosmos.
