Holley Emulsion Basics.

The basic function and anatomy of the Holley carburetor emulsion circuit.

I had a rich condition for the longest time… come to find out my air bleeds were plugged. Just found out about this… thanks for your video

Thank you sir, was wanting to build my own carb from scratch (there so dam expensive now) and was looking for videos so I fully understand what's going on and this video made it click for me. I've always ran Edelbrock

[jdrods]

Awesome video brother!!! Very well explained! 💪🏼 thank you

[rodolfocr]

This is a great explanation, thank you!

[lukesanchez]

Great explanation mate. Loved it and it will help me on this end. I'm keeping this vid for future reference.

It´s actually an excellent explenation. I knew that upper bleeds affect low rpm and vice versa but I´ve never really understood it. The illustration with the straw was perfect even though we couldn´t see the juiice. Well done sir!

Great idea with the straw and juice box! If anyone has ever tried to drink through a straw with a split in it, they will get it!

This is the first video I have seen, and I watch and read a bunch....the first that explains WHERE the AIR bleeds come into play. UP HIGH tends to start emulsify mixture at lower speed/rpm....down low tends to start emulsify at higher speed/rpm. Yep it's the first time I can remember hearing this, I think. So to modify the MIX at low RPM, think up high, to modify the MIX at high RPM think LOW. I'm holding my 1850 metering block, as I write, it has one bleed high, one bleed low. Good job. Now how do I find out about the IDLE restrictions, you mentioned earlier?

Good explanation now all I need is and engine dyno with an air/fuel ratio meter to fully tune a carb for max performance, or at least it would make it easier than trial and error on the street as the carb is much more accessible with the engine on a dyno. Thanks for the info.

What a great video!

A question I've always had: how do the main jets factor in to all of this? Changing them affects the Air/Fuel ratio, so isn't trying to get the jets "right" more straightforward than doing the Air Bleeds at the same time?

Do you know how to make a blow through?

instead of the straw in a drink, think water pipe, and air lift.
