15. The clock is ticking 53 days to the first meeting !
 Better get the engine together then.

The pistons cleaned up and inspected . Then they was inserted into the bottom of the liner (the least worn part of a bore) there was  0.004in. clearance that is the recommended minimum clearance so thats all hunky dorey.








 



new piston ring being checked for end gap funnily enough all 4 compression ring were spot on but both oil rings needed a smidge removing.

 


 
 
Little trick to fit "tight" gudgeon pins into alluminium pistons. Pour boiling water onto piston they are used to much higher operating temperatures so they wont mind. This expands and enlarges the g pin bore and allows the cold (preferably fresh from the freezer) g pin to slide into position. Do not forget to place the circlip facing the center of the engine in first as its easier to put the last circlip in the uncluttered side of the piston facing out .
