It's not any particular brand...they are all equally annoying.
What prompted this rant however was my inability to start my engine on Xmas morning. There I was in the freezing snow, flipping the flippin' prop, swapping the plug, doing all those things we do when our engines won't start. And in the end, just packing up and coming home.
At home, I removed the tank, figuring I'd start from scratch. It was immediately obvious that the take tubes were all messed up. Crushed. Bent. So I took out the stopper (which required some major effort), replaced the tubes, and then found that there was just no way in hell that the stopper was going to go back into the tank.
I think VG's right, screw on caps are the way to go.
