Need help diagnosing a throttle cable & gas pedal problem on my '67 Barracuda

Thanks for the quick replies! As soon as I typed my post, I realized I should probably try adjusting the cable via that harness/saddle thing in between the carb and the fire wall. Sure enough, after loosening the bolt and pulling the cable toward the fire wall and then tightening again, I had my tension back on the pedal. Took an hour to diagnose and about 45 seconds to fix.
