Yes, you have to remove the air cleaner housing to see it.

I should have titled the thread "throttle cable bushing/retainer". The cable end piece pulls against this part to actuate the steel throttle linkage.

If the part fails the, throttle cable moves, but the steel linkage doesn't, so the engine will only idle.

The recall documents package linked to in post #6 has illustrations that show the part and its location.
