Awesomatious! If you're interested in details, read on.
This is an inexpensive diaphragm and piston combo for BS34. It is similar to original. Piston is silver rather than goldish like original. Diaphragm appears to be rubber over cloth like original. Similar weight. Overall impression of good quality. Arrived in about 9 days, from Japan.
You'll need to switch the needles from the original. JIS bits for your magnetic screwdriver handle will be useful.

On the original, remove the two screws then remove the plate, spring, and needle with washer. Note the tiny plastic pin on the needle that fits into a little hole in the piston. Install the needle with washer and turn til pin seats in hole. Drop in the spring, then the plate. Hold the plate down against the spring with a small screwdriver. Put the screws on a magnetic screwdriver and screw the plate down tight. There are four holes in the plate; the two farthest from the edge are for the screws. Massage diaphragm lip into the cutout for it in the carb. It will eventually stay as the folds adjust. Will the diaphragms last? Time will tell. First impression is awesomatious!
