    Ok gents. This saw is odd enough to get me to post a thread about it. I even got my real camera out for it.

    It's not that the fuel injection part was really interesting.....nor the port layout. But the disassembly.

    So here we go.

    Ok.....unplug the wire from the front two connections. The rear connection is just for the kill switch.

    Removing this piece allows access to unhook the fuel lines.

    Take these two screws out.....but don't bother to wrestle with the handlebar.

    Now it just sorta slides apart.

    IMG_5433.JPG

    The injector and wiring. And the reason it's best to pull the fuel tank.

    IMG_5436.JPG

    Then just unhook this little wire here...

    IMG_5437.JPG

    And pull the jug....

    Now a look at the muffler baffle. Just seems to be made to direct the sound toward the recoil side.

    The jug and port layout is pretty ordinary.

    IMG_5442.JPG

    Well.....the combustion chamber is a little different.

    Isn't that black plug on the coil for the soup-can warmer?

    I doubt the guys that designed this saw ever ate soup outta the can.

    Here's why I'm done with the 500s for now.

    Just a few of many.....

    I was really hoping you'd do a thread on the 500i. Thank you for that.

    Looks like you need to get Bubba working on those orange saws.

    How does the 500 compensate for the mods? Does it tune itself? Or does it have to be reflashed ? I'm not familiar with how smart these saws are or aren't.

    Dang I don't follow enough these days. I heard fuel injection was coming but didn't realize it was out. Dang look at all those wires and crap. I like my old school saws.

    More air = more fuel. Simple.

    The harder I make it run.....the more air it's gonna pull into it.

    I noticed that you did not take down the pull cord assembly, flywheel, ignition module, etc. I guess that's all old hat. Something has to be. Right? Also, how easy is it to check for a good spark?
