I guess that's the end of that! The 20" Murray push mower a mowing client gave me has a bent shaft. I was fearful of that since it had this weird pull of the rope, like it was "catching on something" and the shaft itself (with blade removed) was very wet with oil. The blade itself looked really good though: no damage, only rust.

With blade off though, it's clear the shaft is not sitting in the center of the shaft tunnel.

I now know what to check first when someone gives me a mower! :oops:

I'll continue cleaning up the carb and gas tank...........I already have those off anyway.

Anyone have a good shaft laying around they don't want?

A few decades days ago I knew a guy whose main business was straightening bent mower crankshafts. I don't know how he did it.
 
My dad told me of a shop that straightened mower cranks without removing those from the engine.

I doubt anyone does that now.

The local landfill sells lawn mowers for $5.00. I might start checking there.
 
Ring around a few local repair shops.
Because you lot only use bar blades a lot of cranks get bent and B & S makes a crank straitener
 
There is a tool for straightening cranks in the engine. I have one but haven't uaed it in years. Some folks use a hammer but i have never tried that method.
