The 74 914/6 build has a 2.4 L MFI engine in it that came to me running Zenith 40 TIN.
I spoke with a Zenith specialist and he said that a 34m Venturi would be a bette match for that engine displacement and it’s an easy change to make along with some jetting changes etc. This seems a whole lot more cost effective than going to Weber 40ida that are $3,000 +/- just for cores. Anyone here have experience with this they can share? Thanks! |
