Air Fuel Ratio Carb Tuning

[Scott06]

Just catching this thread now.

I am toying with pulling my H-pipe cross-over and modifying it for an AFR meter unless I can find a thread in small diameter Wide-Band O2 sensor where I can drill in-situ...... as I am currently trimming my AFR by tweaking the air bleeds and the emulsion bleeds on the Holley.

I've never seen any O2 sensors with smaller thread bungs, maybe it exists somewhere.

To my knowledge edelbrocks don't have tweakable air bleeds or emulsion bleeds (at least not without drilling) - what affect do they have on mixture?

havent found any small thread O2 sensor bodies either

the adjustable air bleeds is a holley thing as I am tailoring my fuel curve.

Realize they are a holley thing. I was just wondering more air in bleed = leaner mix?

Reason I'm asking - I had to do some work on the idle tubes on my GTO tripower (Rochester 2 jet) to enlarge the openings the gas gets sucked up. Not sure if these are emulsion tubes or not. Not quite as much info on these carbs as holleys. I still have it going to lean (yes I'm hijacking my own thread...) off idle on the transition circuit before the booster takes over ..
