    Chainsaw is running again!
  

*by S***E on Reviewed in the United States 🇺🇸 on January 11, 2014*

My Dad seized his Echo CS-400 chainsaw a while back.  I took the junk parts, drove the piston out of the cylinder and examined it.  Didnt look great, but not terrible either.  Bunch of rust, two opposing minor grooves but no major scoring.  Bought a new piston kit. Re-habbed the cylinder with this flex hone.  They really work well to clean it up and then cross-hatch the cylinder so the new piston ring will seat properly.  RPM recommendations are set by the manufacturer depending on cylinder diameter. Follow those.  Also, don't forget to always use this well lubed with motor oil and clean the heck out of the cylinder with warm soapy water (and all the ports and channels in the cylinder too).  Once you think it's clean and dry, rub a soft white cloth on the inside of the cylinder walls and its likely you'll see its not clean enough.  Do it again.  This cylinder head was aluminum, so I chose the AO (aluminum oxide) grit.  They have other grits for different metals.Chainsaw's running like a champ now!  Good compression.  It's like brand new.  Only reason it's not 5 stars is they're kind of pricey for, essentially, grit-on-a-stick.
