That part seems big to come off the spark plug. Any chances that the piston was replaced and its a remnant from that? Maybe someone missed it on a rebuild?

Madsen's rebuilt and ported that saw at least 15-20 years ago, it was run long and hard until it went kaboom 10 or so years back so I doubt it was left over from a previous rebuild.

Maybe a bearing cage

Maybe a bearing cage

The big end bearing is a bit loose, I don't recall seeing a missing chunk but you might be on to something there.

I found this in the crankcase of a neighbor's 045 that blew up. I'm not sure what it is or where it came from, but it took chunks out of both transfer port bridges and it pummeled the hell out of the squish band and piston.

When a piston gets shelled, some of the bits of piston and rings invariably get shat into the muffler. They fall to the bottom where any goo is, and sometimes get stuck in said goo.
Since an 045 muffler is one piece, it's difficult to verify the presences or absence of debris.


Short of using an endoscope, shaking the muffler to hear if any rings are banging around inside the muffler is best way to tell.
Sometimes they can get loose and enter back into the combustion chamber while rolling around in the back of an empty truck.

I did this engineering mess back in 2018, in order to get use out of an otherwise good oem cylinder. It had a tap broke off in the muffler threads; (not by me).....


I just got it back in last week to replace a failed crank bearing. It was still holding on. Lol

Was that a concrete saw.

I stumbled across this saw at a garage sale in Tulsa. It had been used one time back when it was new in 1965. A veritable time capsule for $40.00 !
For whatever reason, it was ran once, drained of fuel, then sealed back in it's origional box in a guy's attic for the next 50 years. Amazingly, I fueled it up, and it ran like it was brand new. The fuel tank was spotless.. It has it's origional pull rope, and spark plug.

I have the sister of that saw, also used only once (but assembled in Belgium by McCulloch of Belgium)
