Well that was dissappoining..
Not a lot of compression like the others.
Even less once it warmed up...
Not sure if the bore/jug is flexing, just plain not sealing.
Lost power half way through a cut.
I did use a used ring, but I can't imagine it would be that low.
I think i will try one of the hyway big bore pop ups, and set the squish at .020 if that don't do it, I'm done messing with the 56.

Are you sure it didn’t lock up? That’s what the other one acted like to me
Rope pulled easier almost free fell doing the drop test.

Is it losing compression through the area where the sleeve meets the squish band? Once things get some heat and start expanding, maybe things open up between the sleeve and cylinder letting all the compression out? Maybe im just stating that obvious and need to go gfm

It could happen, but I don't know where the compression would go to? And how the liner wouldn't rotate/slide if the jug is expanding that much.
Only thing I can see is everything is so thin the bore/sleeve is actually ballooning opening the clearance up letting the compression go past the ring.
I will try a different piston (pop up) drop the jug a bit and get the .020 squish and see if that helps.

It could be escaping between the sleeve and cylinder once things heat up and is coming out at the roof of the exhaust port where the cylinder and sleeve meet. Also it might just be expanding enough at the top of the cylinder to let the compression escape because its hotter up there but the sleeve isnt moving because the lower part of the cylinder is cooler keeping everything in place as its not expanding as much

Could be, I'll pull the jug and see if anything looks out of place. Check the measurement after some heat cycles...
Meh, everyone does that....
I was worried the top may pop though.
Not gonna like I was very timid with the throttle the entire time. Thought I was holding a grenade...

If you do another one, you could try lubing up the cylinder and sleeve real good with some high temp sleeve retainer before running the sleeve in
Piston looks fine, ring looks fine.
Appears as if those hot spots at the top of the cylinder are low. No ring/wear marks on them
That would explain why the comp drops when hot, goes out of round or the divots grow and blows a bunch of comp below the ring.
Now the question is, with a new sharp ring will it seat in, or wear out....?
The big blue spot below the intake, lines up with where I had a burr trench cutting the first sleeve out.
Must be low spots from getting a little aggressive cleaning the first sleeve out.
