gearing for open arm

Put a Koford 64 arm in a Koford 19 setup last night; ran it about 3 minutes @ 3 vdc... pulled about 3 amps. Brushes were previously used in that setup, so already radiused. 
2 questions... First are the stock magnets good enough for this fierce arm??? & second , How should I gear it?, will be going in a C-06, 120 gram HB1 3/16 x .435 tires.
