Napier second ring with twice the end gap as the top ring. Eliminates top ring flutter.
Remember: This type of ring as with all secong rings is for oil control only hence the larger end gap.


3mm oil is good

Use fish scale and drag the whole package @ 7 lbs.

The key to the whole package is a good straight hone with the correct profile.

Good Luck

Vertical gas ports ?
