  2. Thank you for a very helpful description.
    Does anyone know the flow (e.g. kg/hour) rate through the carburettors, if I should measure with a flowmeter.

    Working in a Zenith carbs solution for a 300 SEL , M116 , 3.5 litters eight cylinders. Have you ideas about it?.

  8. Here we go rebuilding the front carb on my ’72 250C.

  9. Thanks for the information. Can you perhaps give an indication why the suction on my rear carburetor is very weak. The car will not idle at all and immediately cuts out when leaving the accelerator. Valve clearances are correct and compression on all cylinders are 900 – 1000. The engine runs smooth when the accelerator is pressed in short bursts in succession. Kind Regards
