The single most missed adjustment on a carburetor with the biggest effects. don't make this mistake!!!

Hopefully this video made sense. when I started with carbs fuel pressure issues really gave me a run for my money. took me a bit to track the issues down!!!!

I have learned so much about tuning carbs from you. It is truly a lost art and hard to find anyone anymore that can do it well. Im glad you are teaching others

[germanium]

We appreciate all these videos, even years later. Thanks Luke!

I've been tuning for decades, worked with some of the best, and you are lightyears head of old tech. AMAZING! Folk, you will never find more solid old school tech lessons than here.

Luke, it is very kind of you to give all this information for free. Just wish that You Tube and all this knowledge would have been readily available 35-40 years ago. Thank you.

[MLFranklin]

This is really good. Thanks for the good theory and practical examples. And I loved the carb fire going in the background with your calm explanation.

[fxrjoe]

thanks. having issues with 350 chevy in my 77 4×4. your channel rocks.thank you. please don't let the trolls get to you. there just seems to be a lot of jerks out there these days. pepole have forgotten about being polite and treating others like they want to be treated. i am sure that I am just one of thousands that appreciate what you are doing.

[tomnekuda]

Excellent explanations. I've been tuning for 50+ years and I even learned a bit here. I air/fuel ratio change was much greater than I expected. Great video!!!

You are like a carbiologist! Keep up the good work and thanks!

Good information! I don't know how many times I've told guys this. The response is almost always "I don't know, always worked from the factory ". My 65 GTO with tripower is very happy with just over 2 psi but without the regulator the rear carb will flood the engine.
For anyone who thinks "that pressure wouldn't keep my engine running ". That's not true, the pressure remains a little over 2 psi at idle and at 5500 rpm under full load. Yes your carb may be perfectly happy at higher pressure but as stated in this video, too much pressure can and does cause issues with carburetor cars.

Thanks Luke, ive been chasin this issue on my 73 F100 302 with an Edelbrock carb, gonna have to get one of these.

Great videos. You are the only guy I have found on youtube who knows wth he is doing for carbs, fuel flow, timing, etc. I really like your "test rig" truck. Great way to display real world performance to many things most are just told about but never knew if they were real or not and the reason behind it.

I was just researching dry vs liquid-filled gauges and I couldn't find anything that satisfied me. This was the answer I was looking for. Keep up these amazing videos!

[jasonrobinson]

U have helped me unlock the problems and power out of my old car. This saved my day

[HamsterMays]

I just built an 11:1 aluminum headed SBC 383 with a Holley Brawler 750. I'm getting ready to dive into tuning the carb and I'm glad I came across this video! Great information and I'm going to order a fuel pressure regulator TODAY! Thanks!

[sebastianbangheri]

Thank you for your channel just doing a rebuild on a 302 and all your videos have helped a lot! Greetings from Austria

[Jerkwad]

I did a carb swap on my 1994 Chevy C1500, and it worked out great. Your videos were extremely helpful, and you brought to my attention things that I absolutely would have overlooked. Thank you.

[symbiote]

Man I love those trucks. Using your videos to get my 76 f250 back up and running.

[ytwhite]

WOW, I wish this subject would have been brought to my attention about 40 years ago...I have horrible memories of cars that ran very inconsistantly and not being able to find a cause! I had a drag car with an inline regulator and considering the combination(cam with
loads of duration and lift, lobe sep.angle, 2" Hookers, and Holley 850DP) it ran fairly consistantly. Hindsight is 20/20...Very informative
video that makes total sense. I'm now a subscriber even though I don't mess with cars much anymore. Keep it up!

Nice demonstration . I like your setup with the shut off valve, AFR gauge, and manifold vacuum. A vacuum gauge is often ignored as a diagnostic tool.
