Also of interest, the instructions state the cyl is lubed with Graphite from factory, while I had it apart I swapped the bore with Q-tip and no trace of graphite noticed. I also noticed the piston appears to be treated with a service we call "Hard-coat" in my trade, it's possible that some time during the production they made this upgrade but there are small grooves in the piston that would serve to distribute and hold powdered graphite. At any rate I will add graphite to mine upon re-assembly. [ Guests cannot view attachments ]
