Rodney,
About the rudder adjustment, on my 14-19 there is a fixed rudder return spring attachment for the left pedal welded to the tubing aft of the firewall. On the right side, there is an adjustable screw type fitting that connects to the return spring and protrudes through the firewall. This has a stop nut on the front of the firewall which is used to adjust the right return spring tension. By increasing the spring tension, the rudder can be coaxed to remain more to the right when the pedals are released in flight. Decreasing the spring tension allows the left pedal spring to pull the rudder more to the left.
These are ground adjustments only and cannot be done in flight.
Also be aware that there is no rudder pedal interconnect. The left pedal and the right pedal mechanisms are not interconnected in any way except for the cables running back to the rudder control horn. In the event that either the left or right return spring were to break, the rudder would be instantly pulled in the other direction by the remaining return spring.
This would be easily handled by your foot pressure on the rudder pedal with the broken spring, but would probably lead to a wild ride caused by the initial yaw.
Has anyone had this occur?
