More dumb questions:
Is the rotor considered to be at TDC when a radius through the apex is > horizontal toward the spark plugs?
Is another apex  at BDC at the same time?
In ignition timing, is the 30 degrees BTC 30 degrees of shaft rotation > (10 degrees of rotor rotation)?

Now, more serious questions:  in the rotor housing exhaust ports, there > is a baffle near the top of the exhaust

heat the intake.  It seems to me this would defeat the purpose of an 
intercooler.  

Do I  (1) block this off? 

What is the preferred method?  

(2)Grind the lip of the baffle out, slightly increasing the effective

(3)Utilize it somehow?  Or what?

Any tips on how to put this thing back together utilizing ALL the parts > would be appreciated!

Thanks

Chuck Harbert has a three rotor. Chuck?
Also call Racing Beat or Mazdatrix both have three rotors in
the works.
