PEEK Super Seal Rings for Linkert Manifolds
These are the seals many of you have heard about, which will once and for all cure the notorious intake leaks of old manifolds. They are machined from PEEK (polyetheretherketone), a thermoplastic with a melting point of 650°F (343°C). Compared to brass seals this material has superior creep resistance and seal properties and can sustain large stresses over a long service life without significant extrusion.

Bates Throttle Conversion Kit for Linkert
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.
