I actually have one. Used it once to straighten a crankshaft on my own mower. Refused to straighten any for customers due to liability. And the dealer that I bought out was the original owner and was told by him to never mention that you straightened a crankshaft for a customer. Make up some other service that was performed on the customer invoice so if anything went wrong they couldn't hold you liable.
What tools and books are needed to rebuild a B&S push mower engine?

The US banned swing back blades because of the potential for them to come off and injure people but allow crankshaft straiteners

evidently the anti-swing back blade lobby had more money.

More likely the economics won out. Swing back would save a lot engines but of course that means less parts sold over time.

And probably around 500,000 tons of steel a year.
I send about a ton of old blades to a friends foundry a year .
He thinks I am God because he gets a ton of high quality scrap of known composition for free & that is a big win
I get him to occasionally cast motorcycle parts for me so it is a win win
The swing backs are a different alloy so go into a different drum.
Despite doing 3 times as many swing backs as bars, the swing back drum has only been filled once .
The planet is dieing because we are dong things like making too much steel much of which is not being reused or recycled

I have one of those crankshaft straightners. Got it a very long time when an old guy closed his shop. Haven't used it in probably 20 years. I really doubt if i would use it on a customer engine now. I also have the tools to install valve guides. Haven't used them in probably 20 years also. They are in the drawer with the battery hydrometer i don't use any more. I have a 18.5 Briggs all apart on the bench right now getting the cam replaced. Would a push mower engine be worth doing the same? I doubt it.

Boy I hate those Briggs money maker 793880 camshafts. I just returned from a customer that I install a new just back in Summer 2021 and its ACR is already broken again.

Was that one of the Aftermarket cams or OEM?
Would you consider selling that shaft straightener device? I was mowing for a guy the other day and hit a pipe! Old guy had really let his place go and it was hidden in some tall grass. I currently have that mower in the shop for them to try their shaft straightener on it but If I keep up with this business, I assume I'll have that happen every so often.
