Throttle Body: Inspection

Check that the throttle cable operates smoothly without binding or sticking.
If there are any abnormalities, check for
- Excessive wear or play in the throttle valve shaft.
- Sticky or binding throttle lever at the fully closed position.
- Clearance between throttle stop screw and throttle lever at the fully closed position.
