Holley 4-barrel carb rebuild | 4150 / 4160 vacuum secondary carburetor up close and personal

[@Chrxjw]

The quality of this video made me think you had 25k-75k subscribers. Good shots, good editing, quality microphone for the voiceover, quality humor, overall good production. It’s possible I’ll be refreshing a carb soon, figured I would educate myself. There was some dirt clogging the vacuum lines and I cleaned it out with a small Allen key. Other than that it’s unused. By the way I’m stealing that “buy once, cry once” phrase 😂

[@mk1vw_noteek725]

agreed very under rated video

[@thechillhacker]

Great tutorial, but I would add one detail (which you may do later, I'm at 4:56) - if you reuse any metal crush washers used as seals, you should anneal them first, Put them on the end of a screwdriver and heat them with a torch to a dull red glow. let them cool slowly. This will soften the metal and reverse any work hardening from earlier use and vibration. This is particularly useful for brake jobs (those copper guys). If you do this and tighten properly, you can reuse them for years without leaks. I do it to new ones, too.

I want to thank you for taking the time to post this video, it was very helpful and informative. Peace ✌️

Those E-clips are a real PITA. I'm sure everyone knows that feeling when you try to use your fingernails to get the clip on or off and your nail just folds back which painfully reminds you that this could've been avoided if you had just used a flathead screwdriver and pliers to begin with. Also, this video is worthy of a million and twelve views.

[@BurnoutsAndRotorblades]

Let me know what you think about the new camera lens on all these close-up shots

[@Homer54]

Great video! Very clear instructions.

[@jjdiazangel]

The best detailed and clearly visible step by step video. U are awesome

[@Q8motorclassic]

Just bought used junk one. & in my way to rebuild it. Its my first holley carb ever. Thanks for helpful video

[@WeldingandWheeling]

One minute in and I am already subscribing, you do a great job making videos.

[@jonnybravo9729]

This video is amazing, I’ll be watching this again with my carb in front of me. This is the exact same carb I’ve got. Very good video overall.

[@KellyMacklem]

Really enjoyed the video, very nice production. Nice and to the point with a good sense of humor along the way. Well done and thanks.

[@artherrightus7399]

Ok…!!!!…. I am going to attempt this on a 750. I really appreciate this video! It’s a lot of knowledge to retain! Here goes

Ty for this video. You killed it. Id like to see a carb tune up video.

[@spamwagon]

This video did NOT suck in the least. Well done, and thanks for posting!

[@Tibbyturnwrench]

This was quite helpful, tore down the front side of my Holly today. Was in really good shape other than the accelerator pump having a bad seal.

[@lithuaniangiant2676]

Thanks for making this. I appreciate the time you put into it because it saved me time.

[@OlBlueshound]

Excellent video and narration, clear and precise description and directions, i didnt aee your first video but this video definitely did not suck. Cheers to you for sharing your skills the info and your time. Thanks it helped me out heaps!

[@jackmehoff4613]

Excellent vid. Quick, thorough, and to the point.

[@robw7205]

This definitely helped. Easy to see what you were doing very succinct.

[@jasonhergert7573]

Great video that will be helpful when rebuilding my holley .

[@JohnDoe-pv2iu]

I think you did a good job. The only thing I do differently is I disassemble the vacume can. When the carb gets to the point of needing a rebuild, I have found various funk and trash inside it. Nice video! Take Care, John

[@BurnoutsAndRotorblades]

I should have just for the video, but I had just done this one. The car only ran for a few hours before I decided to rebuild.

[@obsessedwithcars219]

Excellent. Thank you

[@coreywalker7356]

Thanks for the video. I’m about to tackle the carb on my 1973 International truck. I know it takes more effort than people realize to make these videos. I rebuild Model T Ford carburetors and made a video about 6 months ago of a Holley G carburetor. Check it out and you can see what Holley was up to in 1915.

[@junkie2100]

i felt the part about the accelerator pump spring... lol. just the other day got the entire carb installed and found the spring while cleaning up :( luckily i was able to pull just the bowl off and fix it quickly

[@harmankardon478]

you don't want the middle inside base plates screws installed as these can drop into the engine. Holley don't put them on their new carbs.

[@dzopf]

Very impressive, my friend. Thank you for making this!!

i thought he was going to get a drink when he grabbed the stool lol

[@jorgeadolfotrejogarcia2235]

My carburetor is the same as that one, but above the power valve it has a small tube with two orings, it is placed in the passage of the accelerator pump. But I can't find the gasket with the shape that fits well with that tuno on

[@Aking6635]

After a rebuild have to buy more part Bc people I bought it from killed some threads

[@jessesiler7061]

Do you do anything about the piston in the choke assembly?

[@JasonPicard-w4o]

I believe my needle valve or float is stuck open. How can I repair it?

[@colinmertes5090]

I got a 4150 and I rebuilt it. It’s a vacuum secondary the back blades won’t engage anymore and the back jets won’t work either so it’s running on the front two barrels idk what I did wrong lol

[@BurnoutsAndRotorblades]

Is there a leak in the vacuum pod diaphragm or one of the small connections between the pod and the carb body?

[@colinmertes5090]

@@BurnoutsAndRotorblades I just got my wisdom teeth removed I will work on the 4150 holly later on unfortunately and fix it. BUT I got a 650 double pump brawler that’s gonna slap right in with some rerouting of the brake booster right to the back and fuel lines and such on the sides and cables

[@slalomking]

What torque is recommended on the float bowl bolts ?

[@BurnoutsAndRotorblades]

I don’t know if a recommended torque, but I run them all down using the cris cross pattern until it squished the seal a bit. It doesn’t take much clamping force for the very little pressure inside the carb.

[@justaprotogen8391]

I think I did something wrong, because the flap at the top of the carburetor won't close, that red thing that connects to the choke, and pushes the flap down, it's just staying down. Why might that be?

[@NubiaMendoza-iw5eo]

Buenas noches por favor cómo se yo con certeza cuál es el pistón número 1 gracias

[@emanuelorozco1439]

I have a Holley 8007 390cfm. It looks the same as this one. Can I use a kit they sell at oreillys or does it have to be specific?

[@BurnoutsAndRotorblades]

I’m not sure. If all else fails, just lay the old gaskets on the new ones and make sure they line up.

What do I do if my accelerator pump squirter doesn’t have the little nozzles it just has holes

That’s what they normally look like. The squirters with the extensions are a little more fancy.

@@BurnoutsAndRotorblades Thanks I put it together and it seems to work really well now. Your video was really informative and I think the carb rebuilt help got my car running.(It wouldn't idle)

Did you pay $137 for the Holley rebuild kit? You did? Why? You didn't? Then how much did you pay for the Holley rebuild kit?

[@BurnoutsAndRotorblades]

I had enough leftovers from other rebuild kits that I didn’t need to buy one for this rebuild.

I just bought a rebuild kit for a 4160 Holley and it was 50 dollars

I did put the wife’s stool back. She didn’t know until I told her about your comment. At the point she wanted to watch the video for context. She didn’t threaten my life until she saw me use her Tupperware to soak the carb pieces. She’s Russian so. . . I’m in trouble.
