    Do you still use acid on a cylinder that has deep scratches? Like one that was seized.
    Great thread!

    If it has deep scratches, through the plating, the acid will eat the cylinder itself, instead of the alloy transferred from the piston.

    Hello!
    Could this cylinder be saved? Is from a Jonsered 2258.
    What should I use to clean it out?

    Looks like a buffing with Scotchbrite would be enough to clean that cylinder.

    That cylinder looks good.
    My rule is to feel without looking..... (that's what She said).....lol
    If you feel it, then at the microscopic level it's a gorge. However, carbon and oil will help to seal it up over time, somewhat.

    Ultra is some of the dirtiest oils out there IMO.
    And probably the worst smelling to boot.

    CristiRo (and everyone else) Be sure to remove that decompression valve and remove the spark plug,
    then carefully clean flush out ALL of the remaining residue from cleaning the cylinder.

    The cleaning pad will leave some (abrasive) grit behind, trapped in the crevices of the the decomp valve.
    This will also be in and around the threads of the spark plug and the decomp valve.

    We wouldn't want to run the engine with that gunk still in the cylinder.
    That would negate all of our work when it scarred the cylinder and piston.

    That's what I just did. ;)
    I also had to clean de carbon build up in the combustion chamber, so the decomp valve and sparg plug had to be taken out.
    All the best!
