Fixing carburetor ball valve problem (saugkugelventil)

Hi guys,
Wanted to share some of my experience that may be helpful for those who got issues with carburetor ball valve (saugkugelventil). The symptoms: when you press acceleration fast the engine loses power for half a second before starting to accelerate. This means ball valve got dirty and not closing properly. I didn't manage to solve it with cleaning tools and came up with another solution. Drill 1mm diameter hole from the bottom as it is shown on the picture, then make few hits through that hole with a screw or something that can fit in the hole. This way you will hit the ball and the ball will push the valve cover out. Now you have the valve opened and can clean it properly and close after. There is no need to close the drilled hole - it will be covered with the seal after you assemble carburetor back.
Posting it in english as it was too difficult to translate in german for me.
