martifers Posted June 12, 2009 Share Posted June 12, 2009 I have used the original Zenith Carb from our S3 LW Petrol 24v on our 1968 12v LW and it runs like a dream. I have purchased a 36IVR (one of those indian ones) and fitted it to the 24V. I cannot get it to slow run without it stalling. The idle mixture screw does not make any difference Being 24v I have blocked the vaccum advance on the side of the carb, but no difference. I set the upper actuating arm on its hole for normal running, no difference. Nothing else has been changed so I guess it has to be the carb Do you think it is just the poor quality of the carb and should I try and source a real Senith or Solex 36IV Any good sources of seond hand ones please?

101sean Posted June 14, 2009 Share Posted June 14, 2009 I assume there's no emmissions control stuff leaking. If not, then yes you probably have a duff carb with a warped top plate. Been discussed in depth a few times on the EMLRA forum. Quote Link to comment Share on other sites More sharing options...
