Does anyone out there have a good photo of the WT-456 carb, with the diaphragm cover off, showing the exact position of the 98-3226 spring?And the inside surfaceof the cover? And perhaps the carb body? The Walbro diagrams are so bad that it's hard to tell how the spring installs. Their diagram makes it appear as if the springassembles around the center screw,but that seems dumb.

It's quite clear that the carb shown on this Saito conversion (see previous photos)won't accept the spring at all. I have some other carbs in the drawer into which this spring might install, but it's not clear if the body or the coverneeds to bechanged to accomodate the spring.

In checking Walbro, there are a variety of diaphragm covers, all which looks the same (in their exploded views)yet have different part numbers. There could be a wide variety of differences, some of which may be there to accept that spring.

With a lot of money, one could just by a bunch of carbs and become a degreed expert. The next best thing is to use the forum. Thanks.
