Port & Polish - or just polish?
I'm about to make some sort of doserless mod on my Robur.
As you can see in the picture, the inside of the chute looks pretty rough and I'm planning to polish it up.
In order to reduce clumping I am very tempted to port it as well (keeping the original size and shape at the inner end and tapering it out to an enlarged exit-port).
This is an irreversible mod and I would love to here what you know and think of this before taking action on it.
Will it work? Has anyone actually tried it? Any thoughts?
