My right carb has been a little rich on the slow side and I could sometimes smell a little fuel. I removed the carbs, to adjust the float level. I had a small square of cardboard, so I measured 17mm and cut it then checked it with my digital caliper. Dead on 17mm. I grabbed a sandwich and a glass of tea. Adjusted the floats, and though they didn't look right, I assembled the carbs and installed them.
Bike wouldn't start. Checked everything and then found no fuel in the bowls. I grabbed my carboard gauge and measured it - 19.7mm. Yep! I threw away the 17mm one and used the wrong piece of cardboard.

Ever do something stupid?

I didn't post this in the tech section because it doesn't deserve the right to be there. Besides, if needs to be moved, Phil will move it. I checked Phil's schedule and he has absolutely nothing to do today.
