I stumbled across these gas port alignment pins while reading on another site (https://www.frfrogspad.com/index.htm). After watching the video, I was asked myself 'why haven't I heard of these before?'
One downside is that at $6.95 a set, they are essentially $6.95 per use if all your gas ports are the same size.
Thoughts and comments?
