Two and a half years ago I spent a lot of time, did a lot of work and made an objective study of the Rochester B and its problems...including a way the everyman can straighten the castings using cheap and commonly available materials/tools. You can see some of that here: https://tinyurl.com/v3oeses

Many other things were considered, discussed, etc. I'd suggest reading as much of what was posted back in late summer of 2018.

Is this a 216 or a 235?
