What is the recommended a/f ratio? I have a 2270 with 44 idf Webers. I have a AEM monitoring gauge Thanks. Dave
Will take a stab @ 12 to 1 ,I want to get one of them myself, .
Depends how stable through the full range, 12.5 to 13.5:1, but on load and cruise you don't want more than 13.5:1 at any time.
Just as an FYI I'll add that with LN Nickies you can push the AFR as high as 14:1.
Iron no more than the 13.5:1
My T4 powered VW bug has Nickies and I run 14:1, you can do this because of the aluminum cylinders superior heat transfer rate.
