Thanks David,

I understood most which you said. I examined my regulator again.
Yes!
The Regulater was single-stage!! The regulator had that sticker(Japanese).

Yes.

It's Best way. But, I don't know the screw of the regulator.
Each screw will have the possibility that is different.
I will find the 2stage-regulator in Japan.

The following is the confirmation of the work which I carry out.
1) Close the hole of Inlet-pipe.
2) Remove aluminum foils of Burner (upper lower).
3) Install 2stage- regulator.
4) Check Gas-lines.

Okay?...  Any other work??

I live in west of Tokyo (about 70miles). The neighbor of Mt-Fiji.
To Gunma, about 100~150 miles.
Do you have the schedule of visiting Japan?
