Holley Air Bleed Size Chart
Holley Air Bleed Size Chart - If changing the mab to a smaller size makes it too rich at wot, change to smaller main jets. If the main air bleeds are larger than.026 or.028 change them to either. Cover one of the idle bleeds and the rpm will pick up a little. Or just the 4 or so wire drills i need au$35 wire drill chuck adaptor au$60 Then fine tune the primary idle air bleed size. I will start with the engine cold, and bring the rpm to around 2000. Bigger bleed/smaller jet/stock (.031) idle feed restriction size is a pretty good recipe for a lean pop and/or lean surge condition at and just off idle.
Au$100 wire drill chuck adaptor au$60 bg blank air bleads x10 au$30 total. Air bleed sizes should not be adjusted more than six (6) sizes in any one direction from the original air bleeds as shipped from holley. There is a relationship between the size of the feed restriction and the idle air bleed. You seem bound and determined to fubar this up.062 pri iab.036 sec iab.
The pri iab will end up being between.062 and.068 It will be real close. Air bleed adjustment beyond six (6) sizes could result in a lean fuel/air mixture causing severe engine damage, property damage, serious injury, and/or death i better not get out of bed ever again either. Just got back from the industrial supplies. If the main air bleeds are larger than.026 or.028 change them to either. Then fine tune the primary idle air bleed size.
I will start with the engine cold, and bring the rpm to around 2000. I would use #72 p and #82 s with.026. There is a relationship between the size of the feed restriction and the idle air bleed. First change all 4 idle air bleeds just like i said to. The pri iab will end up being between.062 and.068

In Order To Avoid Unexpected Results It Would Be Wise To Measure The Air Bleeds, Calculate The Area Because If The Feed Restriction Changes Very Much The Air.
I thought i was going to find a lean idle circuit due to a small ifr, but when i opened the carb up its got.045 ifrs, pretty good size, i didnt expect it, i was going to drill bigger if they were under.035, but it seems to me i should have enough fuel with that big of an ifr.067 air bleeds, but i have run up to.076 as experiment, no change. Air bleed adjustment beyond six (6) sizes could result in a lean fuel/air mixture causing severe engine damage, property damage, serious injury, and/or death i better not get out of bed ever again either. The best p main jet size for wot depends some on the pvcr size. The primary iab tweeks the off idle low speed afr.

Use same size in p & s. The stock idle air bleed i.d. First change all 4 idle air bleeds just like i said to. I usually start with a baseline calibration, set the mixture screws about 1 1/4 turns out.

Bigger bleed/smaller jet/stock (.031) idle feed restriction size is a pretty good recipe for a lean pop and/or lean surge condition at and just off idle. It will be real close. The idle air bleed will also affect the amount of fuel.
I Would Use #72 P And #82 S With.026.
Air bleed sizes should not be adjusted more than six (6) sizes in any one direction from the original air bleeds as shipped from holley. If changing the mab to a smaller size makes it too rich at wot, change to smaller main jets.

Air bleed adjustment beyond six (6) sizes could result in a lean fuel/air mixture causing severe engine damage, property damage, serious injury, and/or death i better not get out of bed ever again either. So you can make the bleed smaller or larger to tune the air fuel mixture just like a jet.
