Hi lms...,  thanks for your reply.  Have checked it by hand/seems a little loose.  I might need to go to the final piston. 

I have verniers,  but what dos one need to measure the piston slack?  I should say here,  that there is a few visable scratches on the piston,  but no goudges.  Have you or anyone else experiemted with resleeving?  If so,  is there AUS engine shops that do resleeving?

Many Thanks In advance.  Post Script.  I have a very good 2nd O/S piston and barrel,  but there is a hairline crack around the lower cylinder mount.  Can this be welded succesfully?  (can provide photo is nec.)

Cheers
