Yes, but that is another subject. I'm sure the case volume on a 660 is quite different also.
I call it harmony, it's not just a set of numbers,it's a combination of everything working together and it's easily felt and heard.It's about balance....
And I've still got so much to learn.
So happy here!!!! This place is the Schiznit!!!!! was so burn't out on the other place,,,, Now I'm enjoying posting again and putting a few of my old project saws together....It's about balance....
And I've still got so much to learn.
I did just the opposite, took a great running saw and made it run like chit.How many of you guys have had a great running saw but thought it was missing something and took it apart and changed one tiny little thing, maybe the entry of the transfers on the exhaust side just a fuzz and put it together and it was like a weight was lifted off of it,then think you learned something only to never be able to reproduce it the same again.
It's not a excact science.

Right on! You learned what not to do!Just gettin it out of the way for the next one
Studies show that if you study drunk, you'll do better taking the test drunk....Just gettin it out of the way for the next one
The minute you think you know it all, it's over for you. An open mind and free discussion is where it's at.It's about balance....

Hahaaa yep me to. I'm realizing I'm dumber than I originally thought [emoji36]I wish I had something to add. Seems like everyday I'm learning something on this site.

We have a roof, that the ring(s) sometimes descend into. Other times not.
We have the floor, the most critical part of the port, as it controls opening, closing, and thus case compression.
We has assymetric designs of both by the OEM. Some roofs have a finger like plate extension for the rings (028S/034 are examples).
Some floors are assymetric, like on the stihl 036 and others. This shape can vary duration a bit because of mix viscosity. At higher rpm, you should get less dynamic intake duration and possibly better case compression. I've personally found the Stihl 036, with an intake floor of 84 after porting, to be one of the most throttle responsive saws I've ever played with.
Is that from port shape, intake duration, the large intake port?
Feel free to discuss if you would like to. I know I'm listening.
