Default Which is the correct A/F ratio ?
Hi guys,
I want to set the correct A/F ratio or lamda for my engine ( Ford FE390 stroked to 445cui with 48 IDA Webers). I installed a oxygen sensor in exhaust on passenger side.....

I was told to set the A/F ratio while idling at about 14.9....what do you think ?

Is the engine with a 12 A/F ratio too lean ?

Can you get me some more information or tricks ?

Thanks,

Stephan
