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)

That a/f meter sounds like a narrowband unit, though I believe it's one of the more expensive ones. I know this isn't the kind of thing anyone wants to hear, but IMHO, they're fairly worthless, and with the sensor so far from the exhaust ports, I doubt that reading can really be trusted.
Light tan sounds right, the CHTs are about right, and it seems to run nicely. I'll bet you're not lean at all. Find someone with a proper wideband AFR meter, and it will very probably show you're spot on, or perhaps very slightly lean. |
