[marcstlaurent]

I’m no, stranger to a Holley and always enjoy immensely your tech videos Randy, thanks very much .

[hemisidetrack]

Thank you very much Randy and camera man, for sharing a wealth of experience with Holley carburettors. It's a great thing that you do passing on years of knowledge to the younger generations.

I like how you say that finding your tune is like R&D - that's what it feels like 🍻

[johng]

Excellent video. I watched the few you have and am using the imformation to modify an Autolite 4100 for use on a 302 with an aggressive Crower. Working on the transition circuit now, thank you!

[kevinbrewer]

I've read book after book on holley mod. and tune but it never come together like you bring it together. Thanks for sharing your knowledge.

Great video quickfuel ss models come with metering blocks that have screw in everything also air bleeds. They are expensive !

Great videos, they have helped me understand how to tune carbs a little more.

Can the air bleeds be modified on the secondary side? I think mine nees a little tuning. I've put the heaviest spring in the secondary Diaphragm, it helped, but hasn't fully fixed my lean spot.

Thanks for posting Randy, but you didn't leave the information on the kit in the description.Thanks again.

Great video. All your videos are great. Thanks. It'd be nice to find one that explains the emulsion jet tuning in-depth, I can't find anything on the topic. It's be especially nice because a lot of the new Holley performance/race carbs are coming with the 5 hole blocks (Ultra XP, Track Warrior, etc.) but that amount of tuning isn't really necessary for a street car and just causes issues. It's difficult to find advise on what to do, or how to modify/jet those blocks for a street car. I've scoured the internet to find recommendations and have actually spoken to Holley tech's about it, no one seems to have much advise. I spoke to Holley just the other day about it, the tech didn't know much, but I did get some spec's for the different carbs (750/850 Ultra XP, Track Warrior) which seem to use the same 5 hole blocks, Holley was able to let me know that they install the same bleed jet stack in all of them, which didn't surprise me... The stack from bottom to top is .029, blank, .029, .029, .029. I was told by a guy that knows Holley's pretty well to go with this stack for the street - blank, .029, blank, .029, blank, so basically a 2 hole system. Going to say a 2-hole system, I would imagine will change the HSB's on the top also..? Thoughts? Recommendations..?

I bought some aftermarket metering blocks and they have a .035" emulsion bleed in the idle feed restriction; at the top of the channel. With those, would it still be necessary to drill the main body and tap it for a bleed? The idle circuit hole on the top if the carb is .065". Thanks for great videos.

[jimclarke]

My 650 vs have blocked air bleeds, sealed brass ports, don't want to drill and tap, just need to know the best way to clean them? thanks Jim

[hondatech]

Broke a tap in a main body trying to add acrew in air bleeds was years ago just playing. I still have the main body if I can get the tap out can I fill the air bleed cavity with jb weld and just drill the in weld?

[mikef-gidg]

After all these years the air bleed/main well picture is now clear. Oh boy!

[freddieanderson]

? About a 4500 holley dominator does it have to have a power value in the front of the meter block or can it be blocked off like the one in the back I'm having problems with it trying to leave off the line

5:40 .... you started to talk about the different locations for the antisyphoning holes in metering blocks, does the location actually make any difference? For practice, i recently modified an early 1850 primary metering block by drilling out just the lower IFR and PVCR channels to accept 6-32 brass set screws that are blank to drill my own holes. All went surprisingly well and i plan on experimenting with it on a 770SA carburetor, but given the diifferent location of the antisyphoning holes, the 1850 is near the top like you have shown and the 770SA hole is inline with the booster opening, coincidently the same location on 3310 carburetors, will it even work or will i have to modify and reuse the original 770SA metering block?

[DaRkmatter.]

can you plz do a video on ajustable air bleeds with air bleed jets

[timrayburn]

Sharon S @ 5:24 he says "here's the tap and the drill made for this, it comes in a kit.I'm gunna leave a description for this in the description."

[grannysgarage]

Tore down a swap meet carb that I recently bought.... discovered someone drilled .035 holes straight through the idle feed restrictor holes straight into the bowl side of things. What is the reason someone did this? Thank you

[andnova]

I need help. Holley 6213 q-jet double pumper 800 CFM, No transfer pump tube. Wrong metering blocks. Primary has 6343, 450 cfm with zero Air bleed holes main well. Rear 4779 750 cfm no power valve. Since this carb had dual power valves the rear metering block is wrong. I was going to install a 1850 primary and 4781 secondary. What is your recommendation ? Thank you.
