Hello,

I used Rod's tutorial for cleaning the rps-34 valve, thanks Rod, shifts nicely going forward, once c-2 spool was loosened up, I adjusted retard screws by trial and error method till upshifting and down shifting was satisfactory to me. I gave tractor to my brother to use on his snow blower, he tells me sometimes when backing up, he pushes in the inching pedal and it keeps backing up, has to quickly slow the throttle to get it to stop, my question, is there something else I need to adjust? Thanks for any and all info, I am learning a lot about these old work horses, Greg
 
Adjust the pedal linkage so it pulls the spool out of the valve a little more. The stop bolt on the top back of the pedal might be up there yet, you can turn that in so the pedal goes down further if it does not go to the floor when depressed. Rod.
