Carbs are overdue for cleaning, my project for the coming weekend. Last time I pulled carbs I encountered the frustration of trying to unscrew the pilot plug screw without stripping the slot, since its screw head slot is specific...pictured below. These screws are very soft, I reckon copper, and its screw head slot is no doubt specific to yamaha. The slot is very shallow, narrow, and long. So I assume there is a "special" yamaha driver that can be bought. Last time I found a driver at walmart that did the job, however since the driver wasn't a perfect slot fit it caused a little head stripping. I'd prefer to not go through that headache again this time around. Wondering if any of y'all have discovered a driver or some other tool that does the job.
