Namco, thanks for your contributions, I find them quite revealing. :)
If you would please, provide some clarification as to your source for the 'tight tolerances' you refer to so much. I am interested in learning both how you know this and what your source is so I can learn this as well as you. :)
As has been said earlier, there are Mitsubishi tecs here. I'm not sure they are following this though. Do you mind if I ask why that would matter? I thought the owner's manual gives the details clear enough.
Thanks! :)
