atpchas - Of course I dumped what you sent before opening thinking it was only a notification. Thank you for sending but... could I get you to resend, please?
MP - No obvious stuck aluminum, some pretty good grooves though. It still had compression so I suspect the saw was run for quite some time burnishing the damage. I'll run a dial bore gauge through it before spending any money. I have a fair amount of experience with Nikasil, you're right it is tough. Is that piston to wall clearance measuring the piston at the pin cl, tail of the skirt or somewhere in between?
First casualty of inexperience; clutch "basket", the part that unscrews. Haven't figured out exactly what I did wrong. No big deal to break it loose, but as soon as it turned it fell to pieces. All three spokes broke away from the center and the outer ring.
