Hello. I'm new to the forums here but have been reading and learning a lot. Thank you.
I have a pair of Weber 40s I plan to use on a 2056 I'm building. The carbs are used, and I don't know how they're jetted. Can anyone recommend a base line? I'm at an altitude of 486 feet. I appreciate any suggestions! Steve |

The chart above doesn't include the IDF.
My baseline Jetting Recommendation assuming 32-34 vents. Smaller vents will require smaller mains. Larger vents = larger mains and nightmare transition issues. May need to go larger on mains with ethanol fuels. 55 Idles F7 ET (F11 will work but may have lean transition w/ 34 vents) 120 Mains 200 AC jets |
