What did you do with whatever else you've got?

Good thinking nick, the peg in the piston is the full width of the groove, I measured the rings and cant see any difference from side to side....very strange, you could be right but I cant spot the difference....might phone the supplier tomorrow and see what he says........head not on yet but still makes a nice plop, plop noise when I turn it over  :lol

Would be interested to hear their answer.
