And while there's a little life to this thread at the moment, here's something I posted to the 357/359 specific thread a couple days ago that I probably should have cross-posted here anyway.
We all know about the intake leak issues with the plastic snap clamp debacle and the associated fixes on the saws that use that intake setup.
I recently ran into another air leak problem with that intake setup that I haven't seen much about. Drove me nuts nailing it down and it probably could have been tuned out, but I rebuilt the same saw for the guy 3 or 4 years ago and it was completely tight when I finished it then. No reason it shouldn't be again.
Here's what I found this time around.

Appeared to be leaking behind the flange since that's where the bubbles were. I'm wondering how the hell that's even physically possible since the boot seals against the front surface of the flange.
Had it apart a few times before pulling the bellows (boot) out of the flange and finding these cracks. They didn't go
quite all the way through and weren't visible from the opposite side. That woulda been wayyy too easy. LOL

Anyway, just a heads up if you service one of the saws using this type of flange/boot arrangement. Most likely a pretty good chance there are more of these out there than just this one. Also a pretty good chance the condition was caused by excessive tightening (possibly by me last time around) of the intake assembly and the cracks occurring over time. That said, I've only heard of these flange threads stripping, not cracking. Regardless, if cracks are present, they'll be hidden if they don't go all the way through the flange. Might be something to consider checking as part of your routine when working on these saws.., especially if you're dealing with a pesky intake leak.
