Saw that one too. Was very impressed. I wish mine looked as nice. At least it runs as well. I have a 21" bar just like the one in the picture. In fact, I got it from z4lunch over Ebay. Only problem is they're both hardnose bars, but I don't think the 075 knows the difference.
You're referring to the 075 on Ebay. No I didn't pick it up. Too nice looking and too rich for my blood. Besides, I like my stuff broke. Keeps me busy when I have to fix it up.
Not sure if you're asking me about the Atom ignition or what?
Real nice saw. Mikes site has it listed introduced in 1974. This saw looks older than the saw on his site. It has the older Stihl emblem. Very nice. I might have to sell some of my saws to buy it, Nah. lol
That saw shown on Mike's site is an 076. Three reasons: The side cover with new Stihl logo, the oil cap on the side of the tank instead of the top, and the hand guard mounts on top of the oil tank. The 075 hand guard was on the wrap handlebar. Those are some funny lookin' bumper spikes too. The last picutre is an 075. Note the differences.
