View Full Version : Which is better - Carb Related

This GT6 MkI block is confusing me to no end. First the bearings are the wrong size (apparently they used different cranks, and not my metering needles are wrong too. My husband discovered that my Zenith Stromberg carbs are not the original MkI ones. He claims they are from the MKIII (from the part number stamped on the original metering needle that was removed.

Question is, which is/was better? New or old? Naturally I would assume the new is better, but I know they had less HP due to emissions. How much more performance would you say this MKIII carb would give me? Or is it like the whole webber deal where no one really knows, and it only matters if its brand new out of the box, or rebuilt. (which it will be anyway)

Unless you are really hopping uo the engine healthy ZS carbs should be just fine. Really easy to rebuild as well, and if your bushings are good cheap too!
