Piston Ring

[Steven]

Hi Steve,
I'm going to do some work on my riding lawnmower, head gasket, piston
rings. Do you know if I need any special tool to replace the piston rings?
Whats new out there? Spent the day last week with Ritchie M. and Davis
at the JLC show in Providence.

I'd start with a crank-bolt extractor.
