And the answer was ?

If you are asking what was found as a cause that is still the not so great unknown. Still doing it (sticking that is) but I have not yet rebuilt the SCV.that is last resort.

Remove the lever for the sticky spool, and rotate the spool 180 degrees.

or

Remove the spool from the bore and inspect, clean.

Remove the lever for the sticky spool, and rotate the spool 180 degrees.
I did that to mine, referred to in post#8, and it had no effect. :confused: ... Does the lever conventionally drive the spool directly? And is the spool a single piece - no swivel in the middle?

The only explanation I could think of when turning it had no effect was that I wasnt really turning the valving part. :confused3:

By turning the spool 180 or removing it for inspection you might get rid of or see the cause of the sticky problem.

While the spool is out ,check the spool centering springs.
