Thanks in advance for the advice, I have a 74 1.8 l-jet and I just replaced vac hoses intake boots and gaskets/fuel inj seals etc. I also installed an air/fuel mix gauge and the gauge indicates that I am running quite lean also my cyl head temp seems a little high too,around 350f so what's the best way to richen my overall mixture so head temps and air /fuel mix is closer to 14.7 or stoich if you will ? thanks again AL (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif)

Where are you running lean? Idle? Midrange? Top-end? All three?
If it's all of the above, look at your fuel pressure, and consider getting your injectors cleaned. If it's only the top-end, how lean is "quite lean"? L-Jet is somewhat known for lean running on top. Also, what air/fuel gauge are you using to check this, and where do you have the O2 sensor mounted? CHT of 350f isn't all that high for a stock engine. It's common to see 300f around town, and 350f on the freeway or pulling up a hill. |
