Question: The Idle Stop screw (#VXR-463080 which is #3080 in the exploded 3 view in the Owners Manual) appears to have stripped threads at the non-head end of the screw. Is this normal?

Answer: Yes

Better Answer: The screw is threaded first and then turned down (made thinner) on the non-head end to engage smoothly in the slot in the throttle barrel. The turned down portion is narrower than the threaded portion. Some appearance of threads may remain after the screw has been turned down. This is normal and does not indicate stripped threads.
