Thank you for this video, I now understand a lot better about open and closed port, as well as other aspects of cylinder design.
Thanks! Now I know how much I never knew! :-\ Very interesting.
Good vid!!
Now, I'm sure I am taking my obligatory shots at a long dead horse.. But I wonder why some saws are of the open port design?? Is it purely a manufacturing cost thing?
This is good information. Thanks.

Yes it's a cost thing, open ports are cheaper to make, most closed port 50cc saws cut faster than 55 to 60cc open port saws, the one exception would be a Dolmor 6400 which has huge open ports and cuts good for 64 cc. Steve
