My STG2SE,s have what seems like a staight cut into the bowl. The short turn is rather steep. I would appreciate it if someone could post a picture of a professionally modified one that would not hurt low flow#s.
There is not much you can do to hurt the flow working the short turn radius. Just smoothe it and roll it back nice and round. Now that I've told you, I'm gonna have to kill you, LOL. Jim Burek
