 I used pieces of exhaust pipe tubing (.062") and Devcon Plastic Steel. I
 formed the end of the tube over the back of the vice jaws to fit the square
 inner ports. I left enough tubing outside the housing to use two hose clamps
 on the radiator hose connection to the intake tubing. Cost should be no more
 than $50.00.
 Using the upper port on a 6 port to determine closing seems fine to me.
 Rotaries are less sensitive to late intake closing than piston engines.

  Lynn,   Why did you square up the inner port?   Jerry
