Diaphragm adapter compatible with your Puch moped featuring a Polini diaphragm intake.
This diaphragm housing connects the standard Polini mounting pattern on the cylinder to a larger diaphragm block. This allows you to mount a compatible diaphragm insert, complete with a matching intake manifold, onto your Polini racing cylinder.
The four-valve version is designed as an alternative to conventional 4-valve diaphragm systems and offers a generous flow path for powerful engines with larger carburetors.
The adapter is mounted using four M5 x 12 mm hex socket screws. The mounting holes are large enough to accommodate M6 screws if necessary.
Note: According to the supplier, this adapter can be used on the Tomo A35 and Peugeot 103. However, space may be tight and require some modification.
You can find the matching gasket and screws in the accessories section.
