If the carb is designed for E85 but it has a fuel curve issue then going smaller on the main air bleed will add fuel at WOT. Fuel curve engineering is best done on a dyno with wide bands hooked up.......
the carb has a quick fuel conversion with the green metering blocks I realize the best way is to use a dyno but that isn't in my future I'm just trying to get a feel for how much air bleeds will change the fuel curve
[/quote]are those metering block's for the dominator or are they for the 4150 series, they look pretty much the same (green)and will interchange, but are not calibrated the same.
