So I recently purchased new weber 44 idf's. They didn't work out well so I went back to an old set of weber 44 idf's that I had. I thoroughly cleaned the carbs, sprayed carb cleaner through all jets, tubes, etc. I have also balanced the linkage. Set the floats, etc.
The car starts well. Idle's well. When I drive the car I get a major flat spot between 1500 and 3000 rpm's. Below and above the car accelerates normally. What changes should I make? My current setup for my 2258 (dual webers, big cam) -idle 55 -main 160 -et F11 -ac 200 -vents 36 Are there other issues that can cause this type of problem (timing,etc?) |

a wide band O2 would be nice for selecting the true correct jet size. guessing jets will add up quickly $$$

My 44 idf secondary cents look different. Right now I think mine are in correct. On mine, the long part is down and the taper is pointing up. |
