6 5/8" ctc might be part of the problem, as I didn't see that listed...... I think we need pics to figure out the problem. You should not have that much slack in the belt..... Read the sticky, "how to post pics".......
When posting, hit the "advanced" icon. Towards the bottom, you will see a "manage attachments " icon. Hit that.... The rest is self explanatory..... If you need help still, just hollar........
