Hey Don, I've been working on several W-1 carbs over the winter and I bought a couple of blister packs of screwdrivers from Harbor Freight. One was their Pittsburgh brand and the other just the generic yellow with the black rubber handles, each pack had like twenty screwdrivers in them. a couple of min on the belt sander or grinder and you can make up a set that will fit the plugs and jets in the W-1. I just keep those special screwdrivers in a Rubbermaid box with all the carb stuff. A lot cheaper than buying special carb tools.
