after the summer hibernation,  my log splitter  now does not return to  neutral  when in auto return.   

It just pulls the  engine down,  and I'm assuming it's going full safety  bypass.

I took the  end cap off the detent adjuster, and there was a little moisture and rust inside it.  

Sprayed some penetrating oil on it,  and seemed to free up the  forward/reverse motion,  but didn't change  the lack of  kick-out.   
Ill try  turning the adjuster  screw in and out a little next.     Maybe there's some  corrosion on the spool that's knotted it up.  
Anyway,   it's  a cheapo  chinese  valve that's  probably  a throw away component.   
If I  get another valve,   how  do I 'size' it?    My  splitter is  14 gpm,  2 stage pump.   I've seen  similar  valves  for sale  rated at  30 gpm,  and  some at 20,  others at 15.  
this is the valve  currently on the splitter
