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?) |

The interesting thing is that my car ran great in the past with the same carbs. I had the same jets and venturis installed then.
The crazy thing is that I found that the secondary venturis were installed up side down by the local guy who rebuilt my carbs. Now that they are installed correctly, my engine runs like crap I have that flat spot but also the engine stumbles when I stomp on the gas. |
