I was just concerned if it looked ok there's also a tiny bit a wiggle with the rod

 

[Blaaster]

The specs say that "F" should be 1mm but you can get away with a lot more as long as up an down movement is minimal

Looks like water inside too? or am I wrong?

 

[heatlbj6]

Well, looks like rust on the crank, and what is the dark oily stuff?
Used motor oil? What are you using for 2 stroke oil?
Normally you'd see remnants of the oil you are using left on the crank there.
I think this explains what happened to the piston.
Possibly from the crankcase? Bad seal? Cracked case?

No I used Yamaha 2 stoke oil I premix sondo I need a new crank also
