I pulled the spool out again, and discovered one mistake I made on reassembly last time. At the end of the bore that houses the return spring, there are TWO snap ring grooves. No telling what the outside one is for, except it is not the right one! Once I moved the snap ring to the inner groove, both positions spring return to center.

I got the tractor so stuck that the underside of the tractor was resting on the ground. My uncle wanted
