I have two questions:

1) All of the shorter valve guide (at the top of the guide) is threaded - WHY?

2) I watched a u-tube video on replacing the valve stem seal on a 235 (couldn't find any video for a 216) thinking it would be the same on a 216 but it wasn't. The shop manual isn't much help. I bought some o-ring style seals but not really sure where they install at (In the valve guides?). The u-tube video showed the valve stem with two notches, one for the seal and one for the keeper but mine only has one notch.
