here is a photo , see what you can see wrong, ski started knocking real loud at 7000 rpm,ill tell you this ,the number 2 piston will move 1/8 inch up and down with the crank stationary.comp 140 120 140 .ski has been slowing down..look close

2 looks lean...detonation that is un-audible can still kill bearings in due time....
ticking time bomb....

Its kinda dark,but looks like the left thrust washer might be missing.If so thats the washer peens on the piston.

Looks like the gaps in the rings are lined up. Did the ring locating pins come out of the piston? That could cause a bunch o' damage.

Also the crank walked forward on you in cylinder 1. Looks like it might be rubbing the front of the case also.

Make sure you get a true and welded crank, That will keep the crank from walking forward.

sorry to hear your bad luck dave,
did you find out about the soot in 3
180 hours aint that many from what i hear,might put my welded one in this winter rather than leave the stock one which will be getting on for 140 hours...
