2270 with Weber 44 is running rich
50 idle. 1 1/4 screw out Had 55. Drives better, but the a/f stayed about the same 135 main 175 air Floats set at 9 with gasket Have wideband sensor 11.0 at idle Light throttle might see 12.8 Decel 13.2 Full throttle 13.7 Is there a air by pass circuit? It's almost the opposite of a air leak Thanks for your help |

Do you know what cam is in there? Lots of over lap can reduce your ability to accurately tune idle mixture.
Your full throttle mixture is too lean as well. Should be around 12. |
