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? |

Good call John. Must have read that wrong after a 12 hr day. That's actually a strange scenario with the main jets the OP has. Idle around 13 A/F ratio isn't horrible, but with a 125 main and an F11 ET, that would, in practice seem actually a little small. I run 135s on a 1.8 with an F11 ET. Any smaller on the mains would be on paper, too small, as would an A/C jet of anything larger than the 210 he has now. But in theory it would lean it out some.
What are the float levels like? Have you set them since the carbs have been on the car? How about fuel pressure? |
