Diaphragm adapter with AM6 mounting, compatible with your Puch moped equipped with a Polini cylinder.
This diaphragm housing connects the standard Polini mounting pattern on the cylinder to an AM6 diaphragm block. This allows you to install a Minarelli AM6 diaphragm insert—the same type used in Puch Gilardoni setups—onto your Polini racing cylinder.
The four-valve design is intended as an alternative to conventional 4-valve diaphragm systems and offers a generous flow rate 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 part can be used on the Tomo A35 and Peugeot 103. However, space may be limited, requiring some modification.
You can find diaphragm assemblies, gaskets, screws, intake manifolds, and carburetors in the accessories section.
