Weber DCNF installation < Previous | Back to index | Next>

One problem I found in my early test drives was "lean surge" -- at constant highway speeds, the car's speed varied slightly, as if I were jiggling my foot on the accelerator pedal. This is a classic sign of an engine that's running too lean. I called MSS and discussed this with Jack Lawrence, designer of the kit, and he sent me a pair of slightly larger main jets to make the fuel mixture a bit richer at highway speeds. Here, I've taken the jet assembly apart (it just slips together, but it's a tight fit) and am ready to install the new jet at right by slipping it into the end of the emulsion tube.
