As you can aee i have a problem my pin for algining my piston sleeve is gone and idk where it is. What do i do now??????

It's not too much of a problem unless it fell down into the crankcase when you were removing the liner. I'd check that fairly carefully before you put the liner back in. Otherwise you can eyeball the alignment or use a close fitting drill shank or wire to guide the liner into position.

Or just line up the exhaust port of the liner with the exhaust port in the case. The exhaust port is the highest port in the liner.

...and once it is lined up tighten down the head...job done.
