Workshop – Air

The throttle valve wave

Where there is air is life – sometimes also a life of its own.

This article is about the original carburetor types of the Puch engines, especially Pallas Zenith 32NDIX and Weber 32ICS. There is excellent literature on this, without which a carburetor overhaul should not be carried out!

The oldi runs strangely, sometimes the engine goes out, sometimes it turns too high. The ignition is fine, the centrifugal force adjustment in the distributor is smooth and resets? What can it be?

Too much air? Wrong air?
They are getting old, the carburettors. They used to do what they should. Cleaning them, assembling a new sealing kit is only half the work. A cleaned carburetor looks good, but an often neglected error lies in the throttle area.

A beaten throttle valve shaft can be easily tested with sensitivity. Is the wave wobbling up and down in its leadership? This is the case for many of the Puch carburetors today. Gasoline leaks and air enters through the wave game. At a point where it shouldn’t be.


There are now new shafts, some with slightly larger diameters and good quality bearing bushings and sealing rings. This can be used to correct the problem described. The testing and overhaul of other components in this context, is not here content of this article.


With the help of precise tools and machines, the holes are revised and restored to target state. In the case of the 32NDIX, it is immediately upgraded to the last stage with X-sealing ring.


The motor thanks it with better conrun, with defined mixture formation and precise adjustment capability. As in the past…

#yourProject – Sealing sleeve – Group 2

What a pigry !

Target state

The sealing sleeve between the gearbox and the half axle is defective. How do you notice that? At the latest at the oil pool under the car, or at the smell of the burning oil on the exhaust parts. Better even more preventive during inspection, then at the beginning cracks in the rubber. But actually in this article it is only 4 small screws…

Many thanks to the companies Autoquariat and Prokschi for the production/distribution of the corresponding products.

Work: 1 hour
Cost: 35 Euro
