Insulator for Linkert carburetors as used by the factory on Panheads, however it will fit all Linkert applications using the 4 bolt mounting flange. It features an o-ring seal on both sides giving a superior seal between the intake manifold and the carburetor.

These manifold clamps are cast from brass and precision-machined. The groove for the O-ring is exactly shaped and positioned where it is supposed to be for a perfect seal. Top notch quality! Delivered with a set of socket head screws and with classic looking hex head screws.

Reproductions of the stock hex head bolts to fasten Linkert carburetors to the manifold.

Aircraft-quality manifold clamps which provide a tight and strong fixation of the carburetor without extra support.

A custom part with a long tradition. This smart little device allows for the use of pull type throttle assemblies with Linkert carbs. After installation the throttle disc will be pulled to open and the spring closes it again, when you release the throttle grip. Each kit comes with two springs to meet individual requirements. The weaker spring (Fn≈23 N) should be sufficient for most outside cable applications, the stronger spring (Fn≈58 N) is recommended for internal or very long throttle cables. Works with all M-series Linkert carbs, when equipped with a 1949-1965 type lever, i.e. OEM# 27260-49.
