:dunno:

Side 3


Side 4

Original rings, seems they just went bad a long time ago. Would it be ok to use a wire wheel to get some of the buildup off (mostly for the piston top), and a buffer wheel to try and polish off the buildup on the sides?

Best way to do it is with 80 grit sandpaper. Shines and smooths in no time at all.

I just figured a wheel would give it a more consistant pattern. I will try that for the sides though. I want to use the wire wheel to get the carbon buildup off the piston top.. i'm lazy. h:

I usually just use a wire brush to get off carbon. Other than that, you don't need to polish anything.

I hope you marked which holes they came out thats a must, forget about polishing you will do more damage then good. Polishing the tops is ok leave the skirts alone

I hope you realize I was joking with my response.

I wouldn't use anything stronger than a polishing wheel with a soft pad and maybe some compound but even then I would be extremely careful.

When removing pistons from a motor you need to know what cyl holes they came out of for a proper rebuild there is now a wear pattern in place Unless your buying new pistons and honing the cyls

Crocus cloth dipped in kerosene. 3M makes it. You might be able to get some at your local parts store.

Whatever comes off with a brass brush and kero or carb cleaner is good enough. They don't have to sparkle.
