Measure the bore. All ya have to do is pull the muffler, insert some solder until it touches the other side of the bore, and gently roll the engine over until the piston makes a little ding in the solder.

Pull the solder out and measure with a caliper. Then you will know for sure.

Yup, this would be a great way to measure it. A 650 piston will be 52mm, a 660 is 54mm.

No flippy-caps, doesn't that mean it's an 066 instead of a 660 anyway?

None of the 066/660 saws have flippy caps. Heres my 660 without flippys. '09 model.

No,660 come with old style caps still.
