Get a magic marker and draw on the rotor housing along the location of

the

apex seal for exhaust events, and along the leading or trailing edges of

the

rotor side for intake events (for a side ported engine) and note how

changing

the timing will change the port shape for each case.

You can also record the events from an engine ported by a third party

and

compare those events to the list.

I seem to be following you mate, I will print this out and reread it a few
times. May be then Jerry's information will make sense to me.

See attached drawings, if it works on web page, JPG and Jif didn't work for
my Autocad 2004 drawings.

Anyhow Lynn where do you get those degree wheels from.

George (down

The htm file you sent won't display George. Get a screen capture program
and use that to capture ACAD drawings displayed on the screen.
ACAD 12 plots drawings to gifs. I am surprised ACAD 2004 won't do that?

Better yet get Rhino and do everything in 3D. The Rhino renderer will
save to a jpg.
