HELP: Piston Rings

i have a petter W piston currently sitting in white spirt hoping the rings will free up as they are currently compressed and stuck to the piston, i tried to remove the oil ring as it looked semi free, unfortunately this broke.

i now need some more rings and suggestions as to how i get the others off witout braking them. Ive sent an email to the guy in SEM hoping he can help me with the rings, unless any of you have a set laying around for a PETTER A type,

one last thing the piston is +40 of standard, although i have been told i can use any size piston rings as long as there smaller.

thanks, Martyn

hope someone can help me

repeated dunking in hot then cold water will have a loosening effect,as the different metals expand and contract at different tempreatures.

A Lister piston I removed had the rings solidly held by carbon. Being inexperienced, I broke one trying to remove it.

In disgust I shoved the damn thing into a tub of diesel and left it in the shed. Months later when I came to look at the piston again, the rings had freed and the carbon was mostly gone.
