Try either of the following combo's:
1. (+)767/purple, (-)766/red
2. (+)767/purple, (-)Putnam green/purple - I know it looks wierd, but its worked to bring up the torque significantly on several P2K2's that were lagging in the past.
From what I've seen, normally the tighter the springs, the more torque and less rpm. However, I've seen more than a few motors where softer springs gave more torque and less rpm. Optimum spring tensions are fickle and really subjective to the brushes used and each individual arm/can.
