Carb float bowl screws
As Qwerty described them, "those %^&^$ float bowl screws", are a pain to remove, and the phillips heads are easily stripped.
The stock screws are not standard Phillips screws, they are Japanese Industrial Standard (JIS) Phillips screws, and are easily stripped with a standard Phillips screw driver
(thanks to Peruano for this info).
If you are going to work on your carb, it would be a good idea to replace them with socket head screws.
On 2001 and newer TW carbs, the stock screws are M4 x 14mm, which I couldn't find at Home Depot, but they had M4 x 16mm. I added 4mm lock washers to take up the extra couple of threads.

At the same time I replaced the two screws on the top of the carb, M5 x 15mm, although I have not had any problem with them stripping.

For about $3.00 US, you can save yourself a lot of grief when working on your carb.
