Tore her down and gave her some decent wash, and removed rear handle assembly with the air filter unit.

A simple but unique construction is this air filter. Her oiler is either simple.

Some of you guys might have interest on her fuel system, it is obsolete but the design still appears to be 'innovative' for her days.
Here quoting a page from shop manual.

Her coil was very old but looks this good! Old things are sometimes more stiff and robust than new, hope a man can be alike.

Metering pin of the day is unique in shape and the size of diaphragm is a tad bigger than that of these days. Also the thickness of the rubber sheet is thicker. So I got one from the States  0.25mm thick sheet vulcanized. If I remember correctly, the original sheet counts 0.35mm-0.36mm to my measurement.
The copper plate sitting in the right is a copy I made for a new one.

Hi Chy how are you?
nice 47 you have...I have a 47A...a few differences between the two saws...a very interesting fuel system to play with, I also had to make metering and pump diaphragms...good fun.
