Hello, I currently have 1974 2.0 and am thinking on purchasing a big bore kit for it. I have a set of Weber dual 40's and distributor set up for carbs that I will be using on the car but do not know the correct main jet size for the carbs (IMG:style_emoticons/default/confused24.gif) . Any help would be much appreciated.

It's an air correction jet instead of a regulating nozzle here in the States. Buy the weber tech manual by Bob Tomlinson. Read it until you understand how the carb works. I had to read it several times before i wrapped my head around all of it.

You'll need to buy a carb cam too. Otherwise you won't be pleased with the performance.
