Probably the best 2 Holley carburetor videos. A great amount of detail and the example runs at the end of part 2 were genius.

@TPVPRO 8 лет назад

Thanks much appreciated

@jefffallen7094 5 лет назад

most informative video i have seen. i love the way this guy breaks shit down for people like my self. without all the unnecessary tech B.S. well done thank you for a great vid.

@sasquachbigfoot9070 4 года назад

I had a old timer show me about 35 years ago how to set those floats exactly perfect front and back before you ever put the carb on the motor. Only need a couple readily available items to do it.

@adriansouthard2936 9 лет назад

I enjoyed that and I don't even know much about carburetors. It was a bit advanced for me but probably just the right speed for someone who has such a carburetor. I see the benefits of liquid courage.

@kurtgarber2950 5 лет назад

For track and safty reasons you need two. Return springs on the throtle

@godwinwelding7172 2 года назад

Very great and informative video. I have a ton to learn about the older motors. Just got myself setup in a 1987 F350 with a 460 gas hawg of a welding rig! I definitely appreciate your video.

Great video. I've got vacuum secondaries, hopefully the second video explains more

Great video brother! Thank you for your help in calibrating my 4150! Very informative. Love how your car set off other alarms.

@NAS-Performance 8 лет назад

This is a fantastic video! I have been having issues with hard launch/engine shut off for a couple of months now. I shock the tires and my Buick pulls HARD all the way UNTIL I lift my foot off the gas pedal ... then the motor shuts off. I don't know if it's getting too much or not enough fuel. I had fuel pressure regulator installed two weeks ago, and it still happens. I am going to use this video as guidance, and adjust my Holley 850 myself. I really appreciate this video. 👍👍

it takes at least 6 weeks for FPR to start working with unleaded fuel

@teleinko 8 лет назад

My squirters aren't squirting. at all. nothing. what's the first thing to check. it sat for a few months without being started up. Trying to get it running right for the summer. great video. best one I've found on RU-vid so far!

@TPVPRO 8 лет назад

Pull the bowl and check the accelerator pump diaphragm for proper operation.

@seletialewis9746 3 года назад

You should mention when you have a flooding Holley just simply remove the top screw and adjusting nut with the needle and seat in your hand blow out the trash reinstall and set your float most likely you need a new filter or clean the fuel tank! I love Holley carburetors 1050 Domnator here!

@mickangio16 2 года назад

And if that doesn't stop the flooding the rubber "O" ring on the needle/seat assembly has probably gone bad. Buy a new needle/seat because you will never find the proper size O-ring.

@beachboy4106 3 года назад

Really informative, well presented, and clear. I rely on you guys to help me tune my car, as here in the UK help is sketchy. Now I finally understand how to get the most from my individual set up. I have a 454 BBC Edelbrock Performer heads, and intake, plus loads of nice internal bits and MSD ignition, but my car still lacked punch , now I have it sorted, thanks. I notice you have Nos, I think I will do the same next, so I will see if you have a video on this, cheers Dude :)

@chriscraft77022 6 лет назад

damn good video... im just getting into holleys. ive heard all that you said for years but thanks for showing it... im starting with the 780 cfm 3310 (because thats what came on my 70 chevelle) i actually bought the 02 sensor before the carb because ive seen people struggle with holleys for years... im a carter/edebrock guy (for driving) but that might change soon... GREAT VIDEO

@TPVPRO 6 лет назад

Chris Craft Yes sir, I believe it's better to see what you're motor likes over the suggestions of others. Thanks for watching.

@ojhernandez2627 3 года назад

I just got a brawler 750 and I adjusted the set screws and idle and air fuel ratio reads between 14 - 15 at idle 13 -14when accelerating and 10 -11 when I come off the throttle any idea why its getting rich?

@chasebecker6054 5 лет назад

@henrydixon3159 2 года назад

@79tazman 4 года назад

I learned with a vacuum gauge setting the air fuel long before there was O2 sensors

@p.shephard2081 3 года назад

Once my car gets to operating temp it wants to die at the light, I've raised the idle to about 700 ram when in drive and it still wants to stall any thoughts? Thanks for the videos.

@normbarrows 4 года назад

power valve, idle mixture, jets: as low as you can go without power loss. pump shot: as small and as late as you can go without power loss. true?

@motorcityracing7319 4 года назад

So for off idle hesitation I should be looking at the cam or pump play with the squirter went up and down still rite off the hit hesitation happen then take off pull fine throw out the 1/4

@79tazman 4 года назад

If you don't believe in a vacuum gauge please explain how everyone set the air fuel before there was O2 sensors because they all used a vacuum gauge and it worked.

@tylers1685 9 лет назад

@ubethejudge69 4 года назад

Curious why at idle you were ok with 15:1? Wouldn't you want it a little more like 12.1, slightly rich , then when you put it in drive it should go up to about 12.7 or so? Thanks? Just curious.

@TPVPRO 4 года назад

NA pump gas 12.5 area is for WOT / power runs. At idle there is no load even just cruising down the highway you want it around 14.0-14.5. If you're idling in the 12s it will load up the plugs over time and cause them to fail.

@ubethejudge69 4 года назад

@@TPVPRO Thanks for quick reply! Ok, I have an O2 installed and just beginning my process of optimizing. I had 12.2 at idle and 12.7 in gear but have yet to drive it. The main thing you are saying to determine front jet size on holley 750 vac and even double pumpers is to do a LOAD , gear down to (auto) and do 2nd to 3rd gear WOT blast and monitor the A/F ... It's those results that one cares the most about? I went from 72 stock jet to 69 just because the idle was super rich to start, I had no idea that adjusting the mixture screws would make that much difference. I also tune at full operating temp 190F. Any advise would be great, I'll even report back my findings. Thank you !

@novafreak4144 2 года назад

Is there a way to tune the idle air without having a tach and getting it correct?

@jakefriesenjake Год назад

Just keep adjusting the idle mixture screws (keep both or all 4, if you have 4 corner idle, exactly the same) until you hear the engine sound the smoothest with the highest rpm. (if you don't have an rpm gauge) If you want 800 rpm, and then after adjusting the mixture it climbs to 900, lower the idle back down to 800. Adjust the mixture again, to see if you can get 850 out of it again. Reset the idle back down to 800 once done. You want highest smoothest idle, while keeping the mixture screws the same turns out.

@novafreak4144 Год назад

@@jakefriesenjake thank you so much!

@jakefriesenjake Год назад

@@novafreak4144 that is if everything else is pretty much what it should be set to. If everything was stock and then you threw in the hugest cam you get get into it, you'll have other things or problems preventing you from even adjusting the mixture screws to do anything at all! Gotta fix that problem first

@colinr6912 4 года назад

So, my Holley double pump carb. If I slightly give it gas. It’s fine. If I rev fast and hard, it sounds like it’s about to stall and then the rpm flies up... Would that be due to my back squirter? How do I fix that? Do I just adjust my rear accelerator pump spring? I got confused by the end of the video hahahaha

@JAMEFIT 4 года назад

I had to stop watching after you said air idle adjustment screws control fuel. Air idle adjustment screws on the side do not control fuel. If so they would be called fuel idle adjustment.

@TPVPRO 4 года назад

It does for idle, if your vehicle is idling with the screws all the way in you have a blown power valve.
