Here's a tip, if your accelerator cable is very loose, get a friend to push the pedal all the way to the floor (with the engine off) and see if the stop flange comes all the way up to the metal stop, if it doesn't your engine is not getting all the juice it could, just to the left of this picture there is an adjustment for it, just tighten it up slowly until the stop reaches the top when the accelerator is floored. You will see a performance increase, dependant on the amount it was off.
