I thought the 32/36 was 300 cfm. Anyway, the 38/38 for me and from what I read with other users, burns more than they'd like. My settings show I need 2 larger sized idle jets than what I have now because both idle mixture screws are 1 and 1/2 turns out for "my" best idle. My idle speed screw barely touches my stop lever. According to Weber I'm running to lean, and I thought I was running too rich. Go figure.
