What do you mean by changing the timing on the spool valve?

Way, i understood if the valve groove is widened or the slot in housing is made wider it change the open close setting of the valve causing all sorts of issues.

Interesting. I hadn't heard about that and just opened my housing up. Maybe I'll find out the hard way if ever get this pile on the trail.
