   Paul,
   What epoxy did Powersport use to glue their tubes in?  Is the same epoxy
   used for plugging the intake passages?

   Joe Berki

   "Hi Paul,

       WE NEVER have used Devcon on a peripheral port sleeve.
   We do use Devcon cast iron to fill the side ports, but that's all.
   We do use Araldite to seal the threads when we screw in the threaded
   sleeve.  WE still use an o-ring to seal the intake from the water.

   Jim builds the p-port differently. He bores the hole in perpendicular
   to the trochoid surface and threads the outer wall and the tube or
   insert as
   he calls it. Then he has a shoulder with an O-ring on the inner wall.
   He then screws the tube in. At that point you must connect the tube
   to the runner with a rubber hose.

   I have recently spent a LOT of time and a LOT of money developing
   the JB Weld process. Deviate from this process at your own
   risk. Believe me... it is not as easy as it looks. There are
   several steps that MUST be done right. One screw up and you
   will have to start over. I made a huge error in the beginning
   by buying the wrong epoxy. Mark Supinski will verify what I say.

   I will be glad to walk you through them again.

   I have cooked JB Weld in an oven at 300 degrees F. I KNOW it does
   the job.

   JB Weld works fine to plug the side ports.
