OK boys, here's what I have learned.
Quality control identified a piston/cylinder defect, (vendor issue), on saws in a certain serial number range. We're only talking less than 200 saws that they are certain of. But the only way to be sure that the problem is confined to that number sequence is to call them all back to be certain everything is OK before releasing them. While this is being done, they are air freighting in more saws so they can FINALLY start selling the dopey things.
It's not electronic, and it's not EPA related.
But, ya still gotta laugh at the whole thing.
Finally a clear answer! We're all huddled around here scheming up all kinds of crazy ideas based on this that and the other thing.
