Throttle Cable

Have you tried adjusting the cable? Loosen the clamp and slide back the housing to take up the excess slack, then reclamp.

After taking the photo I moved it back all the way to edge of the throttle bracket, and that gave me a little more, but I still have about a half an inch of cable that can't be accessed with the pedal.

I think bending the gas pedal actuator up a little might be the ticket.
