Narrative:
At touchdown at dusk in calm conditions the aircraft ground looped to the right at the intersection of taxiways C and D and runway 31. The airplane did not strike the pavement and I did not suspect any damage. I taxied to the ramp to further inspect the airplane before taxing to the hangar. When the tail wheel was lifted off the ground it cocked to the right due to uneven tail wheel tension springs. I just recently bought the airplane and further research showed that the tail wheel tension springs were the wrong size and not properly installed per [the] instructions. I have purchased the correct hardware and replaced all improperly installed parts.
