This video covers how to setup a freshly rebuilt carburetor by adjusting the floats idle air and idle on a Brawler 950 CFM carburetor. Also, if you want to know what to look for if your carburetor is too big this is a clear example of why you do not over carb a motor.

Nice job !
She has a lot of vacuum ! Nice !
Float adjust that I found that works very well is from David vizzard
Turn the fuel bowl upside down and use a number 2 pencil adjust it so it just touches the pencil she will be very close ..
Nice job brother!!
Good to watch someone who knows how to adjust a holley carb correctly!
you are spot on with the larger carb and jetting.. larger venturi produce lower velocity and there fore less head pressure in the main well.. Now get tuning to the air bleeds.. Good Job Man.
Um,,, I have a quickfuel 450 with air bleeds.
It’s on a 232 Jeep- thoughts?
Tyler u rock!! Tuned my 431 Ford FE stroker 4150- 750 DP to perfection ,with a Wideband and your awesome knowledge/vids !!!
I have 750 brawler race carb on a built 350 holly heads runs great right out of the box great carburetor for the money..Great video!
I live in Virginia and ccs carbs in va beach. Guy really cares about his product. I got a 650 hp style main body from him. Its actually 650 cfm. Not 750 ish that proform and others pass off. I got a proform main body stamped 650 on it. Its identical to my 750. I highly recommend rich at ccs carbs. He tailor made that main body for me
Thanks so much for all your tips man i really love hearing from people who know. Your beast sounds very very healthy.
I started off on carbs and distributors. I miss tinkering with them sometimes
You got yourself a unit there bud 🫡
Man!!!!!! That truck Right!!!! Its turning up hard!!!!❤💪👍💯
Actually, the QFT ( and Brawler) 950 Does not flow 950 cfm.. I have tested the flow rates on the flow bench and they come in right in the 830 cfm range.. So it will work very well for a streeter.. and once you go 4.125 bore sb and larger, you will never look at a 4 inch bore again. LOL
Have you did any testing on the Edelbrock 1412 that is supposedly 800CFM??
If so could you please post your findings Pablo Janski. ??
@@mermaiddreams83 get rid of that Edelbrock
The Jet Booster Pix Working Nice TY
Good job take the right way and hope to see you sometime at Budds Creek sad news about capital race way
Once u get that 400 in there u will never go back to a smaller motor if it's like mine they are on another level
you can save yourself a lot of time by adjusting float level dry with a ruler then fine tune it running
Great Video!!!💪👍
I like AED carbs once you start running them you will never go back
Excelente, para un motor Chevrolet 5.7 350 con leva de calle y pistones lt1 es posible un carburador 850 cfm o demasiado grande
Great video
Tyler is awesome thank you for your help
Thanks for the video , I got a question, I got a 455 buick engine with 10.1 compresion, and a got a pro system 1180cfm is that to much
I hope to get help. I have a 67 cougar. It has a 650 double pumper Holley carb. It was jetted from the previous owner. I run rich. It backfires til the engine is hot. I put a spacer under the carb. Helped a little. How do I know that the carb is too big for this engine. Running a 302, with edlebrock heads. Any help would be appreciative.

Didn’t show anything about transition slot. Probably the most important part of setting up initial start up.
Good video
I feel like my 750 carb is a little bit to big for my sbc should I put a little bit bigger jet than the 72s will 76 jets help or work a little better 360 sbc 190 promaxx heads 235 duration cam
first to like ....... when you get rid of the lt1 let me know maybe i would like to take the heads from you🤓
Every one pound of fuel pressure can equal .020 on the float level.
I have and lt1 to that high compression solid roller that I’m having really bad problem with my Holley ultra 850 going super lean after I get down on it through a run then let off and it leans out and wants to dye. The part throttle is bad to. Do you have any suggestions? Oh and the floats are good the fuel system is good to. I just installed a return system so fuel isn’t an issue
What formula or how do you go about choosing your carb size?
I'd also like to know.
хорошее видео!!!!👍👍👍👊👊👊💪💪💪
I have a BBF 472, looking to buy a wideband, any suggestions of brand?
wish you were my neighbor so you could tune my brawler.
Hey man I just scooped a brawler 750 dp for my crate zz4 355. Elevation is at sea level. It keeps loading up at take off. Crack the throttle it shits the bed then takes off. You said you jetted up in the video. Any suggestions?
Transition is not right
Your transition slot is overly open
It should be set no more than 30 thousandths
When you adjust your course idle too far you bypass your idle circuit and lose the transition fuel from your accelerator circuit
This causes you to go lean when your butterflies open causing your bog
Once the main metering comes in your engine fuel ratio catches up and you take off
And here I am putting a 500cfm on a 460 Ford lol......but its a stock cruiser that only goes to 4,000rpm
That is fine only thing you have to worry about is the signal at idle will be really strong. It may load up at idle unless you can get adjust the low speed air bleeds. Just keep an eye on your plugs if they get super fat like black then the idle air may need work.
@@TPVPRO yeah I only have the idle mixture screws out 3/4 turn (Edelbrock) ua-cam.com/video/UYK0P6bLlFk/v-deo.html
