I'm helping my friend get his car working correctly. We are having some carb issues. What is the process for getting the correct idle jets? I have read instructions on the redline website but I'm still having issues. The 914 is a 4cyl 2270 with dual weber 44 Idf's.
I read something about removing the main stacks then driving around. Can somebody please explain this method further. |

There currently is an AEM wideband installed. The car seems to drive well. The problem is the air fuel ratio numbers. It seems that the mixture is always way too rich and if I turn in the idle mixture screws then it goes to the other extreme. It seems like there is a sweet spot with the idle mixture screws that I am having a hard time finding or I simply have the wrong jet size. I think my main problem is that I am getting confused because there are too many variables with the main jets ac... That is why I thought the trick with driving with the main stacks removed may help me isolate and help me figure out just the idle jets then I can move on to the others.
Right now I have 45 idles. The mixture is too rich. |
