Strange they have been out for nearly two years now. BTW the guy in the video is wrong that the new "W" tool replaces the old "W" tool. It does not as it is only for the newer carburetors so you will still the older "W" tool if you work on the older carburetors.
If you research the spiral kit every one comes a new tool which is part of the cost of the kit. If you are a shop that does repairs and buy lots of these kits you are going to have a lot of these to throw away. Personally I don't see a need to buy a new tool every time I install one of these kits. Unless they have changed kits in the last year.
Yes they are using a thin Mylar sheet diaphragm. I still think it will give trouble later but will have a much life span. Most of my customers are not will to pay the extra cost of the new kit so I still install a lot of the older style kits.
