I have dual weber 44 idf's on my 2258. I was having a problem with one of my cylinders and found that the main circuit had some sort of black booger plugging most of the main circuit of cyl 2 and a small on in cyl 3. I completely cleaned everything and reassembled. The car is driving way better. I set the floats at 11.5 without the gasket.
Now I am having the other problem- my car is always too rich. At idle my a/f ratio is 13:1 which is ok for me. If I try to lean it out any more then I get popping on decel at low rpm's. On the main circuit, I am using 125 mains, f11 et, 210 ac and I am consistently around 10.2:1. I can but smaller mains but it seems like I shouldn't need that small of mains. My setup- idles-50 mains-125 et-f11 ac- 210 vents- 34 Any ideas of how to lean the main circuit? |

smaller vents, try 32mm. increase the velocity of the air charge. rich (IMG:style_emoticons/default/agree.gif) If you're not able to introduce enough velocity through the carbs (even though it's a fairly large displacement motor) you're likely to see a rich condition across the RPM range. |
