Thanks for the fast answers!

...I've tried to find one, but where to get a new floater?

I thought that my carb would be running good now, but the car was obviously too slow. (13-14 sec 0-60, '85 360 GLS, B200K)
I've found out that the floating high has a large effect to WOT fueling of the car, so I've tried to adjust it properly tody.

I haven't found a way to get the correct 33,8mm ...
