CNC-milled diaphragm housing for the ADDY GME engine case “Der.prüfstand” on your Puch moped.
The diaphragm holder is cleanly finished, fits perfectly, and features a generous opening of 39.5 x 26 mm.
Thanks to the sloped upper surface of the diaphragm housing and the ability to rotate it 180 degrees, you can adjust the angle of the mounted intake manifold and carburetor to be slightly steeper or flatter.
Note: The housing is designed for installation with sealant. If you prefer oil paper, you’ll find suitable sealing paper in the accessories section that you can cut to size yourself.
You’ll also find the matching diaphragm block, intake manifold, and racing housing in the accessories section.
