Default Engine problem.. piston wont move :(

oh ****.. I oiled the heck out of it and I turne er thru a few cycles.. I examined the sleeve. I really dont think it scored it at all.. The first time it made a slight horrible noise.. AHH!! second time it went through perfectly.
Your right I may have slighty scored it.. but I couldnt see anything. it was perfectly shiny.. I looked at it from all anges.
(trying to say to myself.. you didnt kill it)

well heres a cut-n-paste from my other reply:


Hey guys Check this..

I found out the the engine isnt really stuck. the sleeve is just REALLY TIGHT towards the top!
This makes sense.. this is where most of the action takes place.. so it looks like they actually tapered the sleeve so the top is even tighter!
So I thought it was stuck.. I pretty much soaked the thing in machine oil and hand cranked it through a few cycles.. its smooth now, but still tight as hell!
This thing is gonna need one hell of a break-in! I originally thought this engine had a ceramic head.. it does not!
Anyway.. Thanks for your help! now I'm sorta comfortable having the engines opened

Oh.. important...
They manual says that I should ADD a shim when the temperature heats up. I'm just gonna do it now. I sorta damaged the old brass shim (nor really but heck why not replace it). I'm gonna change it and also add another one.
Hmm.. or I could get smart and add one thats twice as thick
The one in there right now is VERY thin! its like paper..
How are these things measured?

Thanks for all your help guys! I dont know what I'd do without this forum
(I'm gonna copy-n-paste this on my other engine question thread also)
