    I'm putting together a friends Stihl 028av Super chainsaw and I'm confused on how that choke/stop trigger is supposed to be set-up inside the saw. If anyone has a picture of this area of a 028av super I would really appreciate it. I having trouble getting this put back together right where the stop switch will work. Please post any pics for me to look at. Thanks in advance to anyone who replies.

    Thanks Harley T; Does the piece on the end of the wire is what touches the flat brass piece to stop the saw?

    Yes, the tip makes contact on the spring, and it grounds out the ignition.

    That copper strap has to go up to ground out on the crankcase.

    I noticed a wire that was attached to one of the top covers screw. I couldn't kill the saw when I had it running I guess that was the wire that grounded it out. When I pushed the lever down to choke the saw raced to probably 20,000 rpm. What would cause that?

    The throttle lever kicks open the throttle a tad when you set the choke.

    This was like screaming. I was afraid it was going to throw everything out of it before I could pull the plug wire off.
