    Does it have a Macro setting? If so, try using that, with a steady hand, you can get really good detail. Since you gave my box of ribs to Dutch, at lest send me a picture of em!!

    You know I really should get around to reading the book on that camera one of these days..
    You don't actually think Dutch got your slab of ribs...there weren't any left by the time the mailman showed up...
    I got some of that secret special sauce on my fingers while I was attempting to close the styrofoam box...and it being so close to lunch and all.......:hammerhead:

    Yeah, its like most all of the electronical chit we got nowadays. I know on my camera I only know/ use about one tenth of what it can do, same with the computer! But the macro setting is worth readin up on.

    This is interesting. A few years back, I had a back pack blower
    come in the was seized up. Make a long story short, what had
    happened was it some how ingested a peice of arrester screen.

    Funny thing is, is that I had removed the screen years before
    that you fine at the exit hole of the muffler.

    I shook the muffler and heard a rattle, and I HAD to cut it open.
    What I found was a second arrester screen built into the baffles
    of the muffler. Who knew.

    Since then, I give all the 2 cycle stuff the rattle test. Now I'll be
    adding the the 4 cycle mufflers too.

    This is a good thread, I hope you and some of the other 4 cycle
    gurus keep adding to it.

    I will take a stab at it. Could it be wrist pin failure ?

    Wrist Pin Keeper came out of the grove and scored the Cylinder wall.

    Piston pin keeper came out or "step" left at end of pin bore wasn't sufficient and pin worked it's way out. (some mfg have gone to only 1 keeper and not boreing all the way through the piston)
