That sure is a lot of variations, huh?

I try to think in simple terms of 3 carbs for these saws. Walbro, followed by Zama, followed by Zama with primer. And of course the first 2 are interchangeable between saws. So, the real breakdown is between saws with and without primers. There may be some more subtle differences, but everything pretty much works along those simple lines.
