Yes, the bottom of the skirt opens the intake.

Thanks, but I'm now confused regards the inlet, but that's probably because the action there is controlled by the skirt, not the crown and that's what confusing me. I guess I need to make a degree wheel up and prove it to myself!
thanks again
You're just making it more complicated than it has to be. At 80° before, or after TDC, the skirt of the piston is even with the floor of the intake port.......

I was just about to post, and the dogs are going crazy, and guess what is in my driveway, a guy with a foreign 660!!!
First thing I did is check the P&C. Porting on this one looks perfect! The squish band has a very slight irregularity that made minor marks on the top of the piston, but overall it looks great, I may not touch the ports!
Anyway, I was going to post, so case compression will be determined by when the intake closes and before the upper transfer opens, right?

Yes. Primary, or case compression as we refer to it is measured in degrees of crankshaft rotation from intake closing, and transfers opening.

True Story, happened several years ago ... I usually don't talk about religion, but when 3 Jehovah Whiteness knocked at my door and asked to come in, I said sure! You want to discuss religion with me, you better be on your A game.
Bottom line, they had to return the next day with their supervisor to explain to me what they believe, and he walked away!
I believe that everyone has the right to believe what they want, but when you think you have the right to tell me what to believe ... Watch Out!!!

Ha ha! I do tend to want to know the precise details of everything, yes - well spotted! But yeah I'm getting my head around it now, and as said earlier will sort out a degree wheel rig soonish and prove it all to myself. Thanks again for your time.....and patience

Gotta match up a bunch of mufflers to the jugs? Make a pattern.
This one is getting worn out. But.......you get the idea.
