Jon in the past you and I have agreed the work done by Carter engineers ought to be accepted and followed. In other words, Carter designed certain carburetor models to work best on certain year ranges of the 235 and because of notable changes in the 235 a person's most sensible option with regard to Carter carburetors would be to find the model Carter had designed for the particular engine he or she owned. Has something caused you to move away from that idea?
