How to Set Four Corner Idle Mixture Screws on a Holley Carburetor

[@adamrodenberg1557]

When adjusting the idle blade position, I've found sometimes using different sized PCV valves can help get the idle in the range you want.

Thanks for sharing. Yes Good demo. 👍

@@VinoRatRodbuilds thanks bud!

[@PACBrian]

ah. thats a good way to do it. i was only using vacuum on mine. will try going by rpm. good looking carb man!

[@MuscleCarSolutions]

@@PACBrian for sure. It’s a good way to get it settled and can verify vacuum as you go. Thanks man! It’s a little different but I like how it came together as a Frankenstein mix of parts.

My friend has a 1967 t bird and his factory carburetor was not working well I had a motorcraft 4180 as a spare and put it on his car and runs very nice

Hi I appreciate your knowledge and love you videos. Hoping you can possibly help me i have a Edelbrock 1806 AVS Carburetor that I bought used looked complete but found out it is missing the butterfly secondary piece any suggestions where to find one? Thank you for your time.

[@MuscleCarSolutions]

@@meek01__53 what piece?

[@meek01__53]

@MuscleCarSolutions is there a weighted butterfly for the secondaries on a 1806 Edelbrock carburetor? Getting conflicting answers.

[@MuscleCarSolutions]

@ no. The thunder series carburetors use the air valve secondaries. The performer series carburetors use the weighted air valve.

Awesome info!!

[@MuscleCarSolutions]

@@hybridmusclegarage4590 thanks man

[@mikeymike758]

Just curious, where is your pcv vacuum coming from?

[@MuscleCarSolutions]

@@mikeymike758 the engine vacuum through the carb is what pulls through the PCV to clear the engine.

[@dickeymoore3662]

Where are you located and how can I get my carburetor rebuilt and quote on rebuild?😮

[@MuscleCarSolutions]

@@dickeymoore3662 I’m not currently offering a rebuild service. When/if I resume it, you can check my website for that announcement.

[@professorgreen1215]

I thought that while adjusting the adjustment screw, you had to get the highest vacuum? All that time, you did not even talked about vacuum. Am I right?

[@MuscleCarSolutions]

@@professorgreen1215 there wasn’t enough variance in engine vacuum so I switched to engine RPM and (hopefully) that’s clearly visible on the timing light seeing the RPM change as I turned the mixture screws.

Drop aces killshot efi your done.

@@apocolypse11 aces is the new revamp of fitech. I’d rather pay a monkey to sit under hood and manually dump raw fuel down the intake than run that garbage. They were smart to start that brand to confuse folks. The fitech name and product is junk.
