        Ok guys wanted to thank everyone for all the help.. got one more questions…I have attached a couple of pictures of the piston one shows the piston before I removed it from the shaft the other shows a pic of the parts catalog .. it appears that the parts picture is reversed from the way it was installed? Can anyone clarify if the piston is up side down and also the best position to place the ring gaps.. the last picture is side view of it all cleaned up with new rings..thanks
