What are the challenges with using Zenith 40 TIN carburetors on a 1970 914-6 engine?
My understanding is Weber 40 IDTP would be the correct original carb. I also understand that 1970 911T came with this model of Zenith. So in theory, no problem? We are trying to decide if we should rebuild these Zenith. If they are essentially same fit, form, function as the Weber, we will probably keep them. If there is some domino effect of now that you're using Zenith you also need to replace / modify x, y, and z, then we will probably try to source some Webers. Thanks for sharing your experiences. P.S. Would I be correct in understanding that the key concern when evaluating the carbs for rebuild would be:

the zeniths are a pollution carb, but if you have nothing else rebuild and use.
