Oh no. The bitterness of cheap tools has lasted long after the savory success. Feel free to pile on Harbor Freight. :-)
On the carburetor float bowl screws, I use Vessel Megadora. I have 900, 920, 930 and 980 (KDX250 KIPS retaining screw anyone?).

On the jet block screws, for anyone shopping for a tool, I strongly suggest NOT getting a short bit. There is some metal in the way that makes it hard to use. It needs some clearance. I need to shop for a better solution. I am tempted to try to drill out a hole in a regular T-20 screwdriver. Maybe it won't break my cobalt bit.
