With old, complex technology like this, the veterans who really understand the design behind what each little passageway does are rapidly dying off. We've got the video technology to record those details, if somebody will go through the effort. This video series is a great start.
Always good to see your comments spelunkerd. Ryan, you make me laugh. My first car was somewhere between injected and carburetated and no one I could find understood it. I'm very glad that this is a way to preserve the knowledge too.
What an amazing resource! I, too, own a 1979 Ford Fairmont with the Holley 1946 carburetor, and have been wanting to improve its cold starts. This video has given me the confidence to try it! Carburetors don't look so mysterious after all. Thanks, EricTheCarGuy!
I work on old VW beetles and the choke adjustment has always been a thing I never understood quite good. Thank you very much, Eric, because thanks to you now all the chokes I adjust end up perfect and my customers happy!!
Nice video Eric. It seems to me when you are doing adjustments that when you do a full turn on a screw you do that correctly but when say you "adjust another half turn" you do a quarter turn instead. To me it's not nit picking if you are adjusting carburetor choke and idle air and things like that. Precision is important. I love your videos and watch them quite a bit. Keep up the good work.
10:08 For anyone wondering: HIC = Hot Idle Compensator. Via a Vacuum hose It controls a valve that opens / closes the stove tube which can bring in fresh air for the carb after its passed over the exhaust manifold to heat it while the engine is cold & also allows additional air to go into the carburetor when the engine is hot to avoid the engine getting wonky at idle when hot.
Hey Eric I noticed after performing the adjustment with the vacuum pump you were supposed to turn the screw 1/2 turn but you only turned it 1/4. Hope it doesn't affect things too badly. Keep up the good work :)
Thanks for making these videos, sharing know how. I'm an old diy about to do some work on my veteran Mitsu 1,6 carb. Haven't done any such jobs for some decades, the carb somewhat more advanced than any other carbs I've put my hands on, and no one around to ask any longer, I'm a bit anxious for the results. Your videos on the subject are encouraging. Good cameraworks too. Thanks again.
Makes me glad I don't own a carburetor vehicle. Looks like a pain in the ass to deal with. You're certainly learning a lot here Eric and bringing us along with you. Thanks!
William Todd O_o Of course you need to unplug the harness. You're trying to set an accurate base line, not compensate for the the computer's programming.
William Todd Things that "go wrong" with EFI usually involve sensors, which average 5-10 minutes to replace if that and require no dealer tools. Actual PCM failure that is not a pattern failure in a specific vehicle is uncommon (although it's sadly common to see shops try and sell PCM failure when they don't know what's wrong).
Rýán Túçk It's not some vague setting that has the engine running. The adjustments targets specific fuel mixture and rpm ranges. Set it wrong and the computer won't have the full range of compensation it normally would. So yes, it's a base line. I've seen some where the settings were so far off the computer locks at full adjustment and they're wondering why they are having issues. Of course, I use the term computer very loosely, it's such a rudimentary system.
I haven't needed to rebuild a carb and I might never, but they've always been a black box to me, like an auto trans, I really don't want to touch them. Great video, Eric, it has made a carb rebuild a lot less scary thing. One point though, two times in the video you said to turn the screw a half turn, and you actually only turned it a quarter turn, both times. Great video.
When I was 8, I lived next door to a auto mechanic shop. The guy there was really nice and he would let me hang around and watch as long as I stayed out of the way. One day, he gave me a little tool kit and a carburetor, and said "Hey Slick, fix this for me would ya?" I spent the next week taking that thing apart. Then I spent a week trying to put it back together just putting random screws into holes to get all the parts on somehow. Honestly it didn't really teach me anything, but it really gave me a mechanical mindset, and now I've loved this kinda stuff ever since.
Thanks i have a 1 barrel carburetor to work on and this video is very helpful in teaching how to get oriented with a carburetor's parts before attempting first time adjustments or disassembly.
This was great. i have almost the exact same car and was looking for a general knowledge and here i find you working on the same make/model/engine that i have only yours is a 79 2 door while i have a 78 4 door. thank you so much
HIC = hot idle compensator. This is an earlier version Ford used, and it is important. It is designed to raise your idle when hot, to help keep operating temperature down. Higher idle = faster engine rotation which means your cooling fan spins faster at idle = more air flow through your radiator.
Thanks for the awesome video! I will be rebuilding the carb on my '86 Toyota pickup, first time for me so this really really helps a lot.. will probably re-watch a bunch of times haha. Cheers Eric.
In case anyone was curious about HIC. HIC is hot-idle compensator. During extreme heat idling situations, such as sitting in traffic, the engine temperature can heat the fuel and cause vapors to leak into the fuel flow. Without the valve, it can cause a rich fuel mix. So, this valve allows more airflow in at a certain temperature.
Hmmm. Almost bought an 82 rx7 with a carburetated 12A rotary but was scared and wanted FI. Tried for a 84-85 gsl-se that has a 13B FI engine but ended up with a 96 miata. ☺
Thank you for this video. It's clear, concise, and thorough! Sadly the carb I was hoping to work on is one of the later models, with an absolute snake nest of hoses, and I'm now thoroughly convinced that it's not a good idea for me to try to mess with it, and I sincerely thank you for that, you probably saved me way more headaches than it would have been worth.
Dear Erik, I think that the notches on choke adjustment is meant to adjust it to more tension side at winter (depend on winter season in your area harsh or mild) and to adjust it to lesser tension side at Summer. Your videos are Great, Thank You.
try putting just tiny bit of hylomar on your gaskets when you re-assemble (a discovery I made when I had some leftover). It really helps keep it the parts lined up while you're messing with those little screws.
one of the left over gaskets looks like it has a cutout for to allow space for the part that part that was warping the plate. looks like it goes black gasket then green gasket then plate. Could be wrong but it looks like the right shape and would allow for that thicker seal to go under the valve. great video!
Thank you for sharing your knowledge so freely it’s very helpful to me, now l have a Carburettor problem with my Ford Econovan I don’t understand the problem my mechanic were told me about by see this video I have learn and understood thank so much I wish you were near here I live then I would like be your customer.
the choke adjustment is the best after putting it in the fridge for an hour or if you have really cold winters cold place, put it in your freezer, then adjust it
Hi Eric, I would definetly not put silicon anywhere near the inside of a carburettor, usually finds it's way into the jets and blocks them up, I would have prob taken the stud out of the nut and refitted it properly, but I have just wound them in so I know the feeling...cheers good video, think the worst one I ever done was a Volkswagen schirocco, I normally fitted an inline filter when I had finished...cheers Fred UK,
thank you for the video! i'm sure everything's been said before, but i noticed one of those leftover gaskets should be the choke thermostat's round gasket. also, the vacuum line you plugged could be(?) a manual choke thermostat warmer, instead of the electric line you have now for the thermostat.
On both screw adjustments (idle mix also) he only went the quarter turn. On the idle he did a complete once around for the one and a half, then only a quarter turn to finish.
Rýán Túçk Haha!! "Everything in the automotive world is doubled. "Four" cycle engines only rotate the crankshaft twice completely for double the operations"... Your are WRONG. Four cycle engines Have 4 actual cycles... That is not and NEVER was a reference to the number of revolutions of the crankshaft.
Gotta ask. Why is there what appears to look like coolant pooled just below the valve cover at 23:46. I assume you missed the hole pouring some in. Just curious about it.
What you refer to as a motor, on the carburetor, is really a solenoid. Most likely, the windings are open because the wire going to the connector has broken-off. Taking a part the solenoid and repairing the broken winding may fix the solenoid.
I'd think twice about pulling that tractor six...there is something about those old motors that put a smile on my face. Too bad it doesn't have a column shifted 3 speed.
Hot-idle compensator (HIC) valve. When the temperature rises, the bimetallic strip opens the valve and allows air to enter the throttle bores under the throttle plates, which leans out the idle mixture and raises the idle speed. Higher idle speed makes the water pump move more coolant through the radiator and makes the fan move more air, thus preventing overheating during extended periods of idling.
Nice video very informative my father has the same car same color and interior color to and it has been setting in our backyard for more than 20 years he stopped because the transmission went out and we did not have money to fix it so it stayed there so I will start by doing this to the Car fix the carb and new gasoline pump because is mechanical and trie and fix it for hi to drive again thanks and keep the good videos coming
Eric, You sure that one of left over gaskets wasn't for the HIC cover? That would make sense as to why it was sitting higher with that other new gasket installed. Cheers Eddie
Also! Anytime you reassemble a carb; you can use 2 stroke oil as a good carb assembly lube. I always do no matter the carb. It can mix with the fuel when the carb fills and burn off and ensures everything goes together smoothly!
As of the missing vacuum line, it is probably the purge line for the charcoal canister that have been cancelled because in the carburated engine era , no body pay attention to this feature and the result would be a gasoline vapor smell, just FYI.
Again, observation.... If you rebuild a Carb for your permanent use, I'd strongly recommend using Blue Loctite on all Body and Throttle Screws. Something we only learned later, Fuel doesn't get into most of those threads. Carburetors by nature, usually shake SOME screws loose over a short period of time. 😉
Eric I really think you should start a kick-starter or a patreon to get money for the engine. I don't think there is anything wrong with it and you would be guaranteed to get the money extremely quickly! (I would gladly donate!)
This was an awesome mini-series of videos, super informative...any guesses to what a mechanic would charge (or should charge) for the same rebuild you just did?
I was curious so I searched for what HIC stands for : HIC Hot-Idle Compensator Some later model Motorcraft 2150 carburetors have a hot-idle compensator (HIC) valve mounted on the back of the air horn, behind the choke tower. The HIC system consists of a bimetallic strip attached an air valve, and special air passages inside the carburetor’s main body. When the temperature rises, the bimetallic strip opens the valve and allows air to enter the throttle bores under the throttle plates, which leans out the idle mixture and raises the idle speed. Higher idle speed makes the water pump move more coolant through the radiator and makes the fan move more air, thus preventing overheating during extended periods of idling.
Very good job! I’m an carpet cleaning in Chicago ands I use a power steam machine goes inside the van & needs carb work done I would you do it old machines but it worth
My granddad was a specialist for Chevrolet for 25 years and people would come to Texas from California just to have him tune their cars. He always taught me to soak the new gaskets in gasoline before putting them on the carb. Do they just make the gaskets different now or could this explain why the new HIC gasket wouldn't fit?
Eric, Love the video! I had my 2 barrel rebuilt and it still doesn't run smooth. It sits atop a 1985 318 Ram charger and floods when trying to start when cooled off. I smell a little bit of fuel when driving and after watching your video I'm wondering if my mechanic missed something. There is much to miss. I've returned a few times to get it fixed but it still does the same thing. Any suggestions? Thanks, Flooded in San Diego
Erick I'm big fan of the power probe myself. However I bought brand new power probe master kit at a local pawn shop and the directions were missing. I have figured out many ways to use it but feel like I could use some Viagra type education. Thanks, Jack
Do you have a video on how to adjust the fast idle cam? I have yet to find a video where anyone actually explains how to adjust it :(. I don't know where to put the adjustment screw on the stepped wheel
HIC Valve - Hot Idle Compensator Valve : when engine reaches a certain Temp it opens and sends more Air to the throttle plate to go to the engine compensating for the high temperature air reduction
I noticed that too.Yes, it would have to be leaned in higher altitudes. Enriching the mixture would foul out the plugs. You would want less gas in the fuel/air mix.
Hi Erick, great video I have a 1989 Toyota 22r truck, my choke plate dont move when is cold or hot stays at the middle like when is hot, I remove the choke,and even like that the plate dont move, like is stuck somewhere, please help, cheers from Ontario calif.
This looks so much more complex than my motorcycle's carburettor, but I bet this one has a lot more functionality to it with that increased complexity. At least I hope... I really enjoy simple but effective designs, I reckon that is why I am stuck with two 2-stroke motorbikes ;p
Fixing up a carb that's exactly like the one here, do you have any measurements of that small pin that goes in with the bearing ball? Didn't have any of it in mine either.
Hey Eric , Last time i checked my carburettor and cleaned it , it was quite dirty , usually i just put regular 95 octane Unleaded into my tank , is it true that Gasoline additives like Wynn's work at all?
My one barrel Holley has no tag...lol, ah shucks. I have a 78' Dodge LA318 with a tag-less one barrel as I said Holley, so how how would I go about on that?? The service manual, Ramcharger, yeah, I got one of those lol I think the service manual is worth more than the vehicle, but I digress, the manual goes into great detail on a two barrel....I'm very sure it's a one. Might be good to switch to a fuel injection system...fun!
With old, complex technology like this, the veterans who really understand the design behind what each little passageway does are rapidly dying off. We've got the video technology to record those details, if somebody will go through the effort. This video series is a great start.
?How did the Million Dollar Man lift cars if his spine wasn't bionic
Always good to see your comments spelunkerd. Ryan, you make me laugh.
My first car was somewhere between injected and carburetated and no one I could find understood it.
I'm very glad that this is a way to preserve the knowledge too.
+DE Nichols My truck is like that because it's TBI, or Throttle Body Injection. Which is pretty much a carburetor with electric squirts at the top.
Koshunae cool. What's your truck?
Rýán Túçk I know right? Why'd you say that? Oh because we had the technology. Touche.
What an amazing resource! I, too, own a 1979 Ford Fairmont with the Holley 1946 carburetor, and have been wanting to improve its cold starts. This video has given me the confidence to try it! Carburetors don't look so mysterious after all. Thanks, EricTheCarGuy!

It’s always amazing to me that people were able to design these complex parts
HIC is "hot idle compensator", it allows a small air leak on a warm engine to reduce idle speed.
Could you please explain how it works?
10:08 For anyone wondering: HIC = Hot Idle Compensator. Via a Vacuum hose It controls a valve that opens / closes the stove tube which can bring in fresh air for the carb after its passed over the exhaust manifold to heat it while the engine is cold & also allows additional air to go into the carburetor when the engine is hot to avoid the engine getting wonky at idle when hot.
It would be nice to hear the car running with the rebuilt carburetor, and then a comparison.
You know back it the day, tuning cars was much more of an art. Much more satisfying to do than today with modern electronic everything.
Eric, HIC = Hot Idle Compensator valve. Your educated guess was spot on!
Eric I realy appreciate all u are doing in the world of motors u are truly kind to share your expertise and help others.
Hey Eric I noticed after performing the adjustment with the vacuum pump you were supposed to turn the screw 1/2 turn but you only turned it 1/4. Hope it doesn't affect things too badly. Keep up the good work :)

William Todd Even most old timers think computer controlled fuel injection is the way to go. I guess they had to start that marriage somewhere.
William Todd O_o Of course you need to unplug the harness. You're trying to set an accurate base line, not compensate for the the computer's programming.
You're trying to set a usable limp-in mode, not an accurate base line.
William Todd Things that "go wrong" with EFI usually involve sensors, which average 5-10 minutes to replace if that and require no dealer tools. Actual PCM failure that is not a pattern failure in a specific vehicle is uncommon (although it's sadly common to see shops try and sell PCM failure when they don't know what's wrong).

I HAD TO SUBSCRIBE TO YOUR CHANNEL!! I LIKE ALL THE INFO AND DETAIL U PUT INTO EXPLAINING THE REMOVAL, CLEANING, AND REASSEMBLY!
Thanks for the video, but what is the output? Is it successfully ? Why you didn't start the engine?
No, it has to be flow- tested on the bench next.
awesome videos man keep up the good work very informative

At 14:50 you turned it 1/4 turn Not a half turn.
On both screw adjustments (idle mix also) he only went the quarter turn. On the idle he did a complete once around for the one and a half, then only a quarter turn to finish.
Everything in the automotive world is doubled. "Four" cycle engines only rotate the crankshaft twice completely for double the operations:
Rýán Túçk Haha!! "Everything in the automotive world is doubled. "Four" cycle engines only rotate the crankshaft twice completely for double the operations"...
Your are WRONG. Four cycle engines Have 4 actual cycles... That is not and NEVER was a reference to the number of revolutions of the crankshaft.
I saw that too

Eric, each time you did "and a half" you actually did a quarter.
I was about to point that out.
It freaked me out every time he did it xD lets hope he sees this :)
I noticed that too. Glad I checked the comments before I doubled yours.
Today ERIC THE CARBURETOR GUY .
Where do you buy a motorcraft carb rebuild kit?
What solution did you use to clean the carburetor?
Really enjoyed watching this!!
That was great Eric,...I like basic.
Fuel injection might make it easier but it sure is more expensive when the O2 sensor or the computer craps out.
Nice video very informative my father has the same car same color and interior color to and it has been setting in our backyard for more than 20 years he stopped because the transmission went out and we did not have money to fix it so it stayed there so I will start by doing this to the Car fix the carb and new gasoline pump because is mechanical and trie and fix it for hi to drive again thanks and keep the good videos coming
Eric, You sure that one of left over gaskets wasn't for the HIC cover? That would make sense as to why it was sitting higher with that other new gasket installed.
Cheers
Eddie
lets see a video of the first start after the rebuild... and / if any adjustments need to be made - thanks and great channel
just think how smart the person was who said" ok, this is it" to the final design.
Also! Anytime you reassemble a carb; you can use 2 stroke oil as a good carb assembly lube. I always do no matter the carb. It can mix with the fuel when the carb fills and burn off and ensures everything goes together smoothly!
i like my carb and im sticking to it
Are you going to do a part 3 of adjusting the idle and such? That would be nice.
those straight 6s can put out a whole lot of HP and still keep good driveability
As of the missing vacuum line, it is probably the purge line for the charcoal canister that have been cancelled because in the carburated engine era , no body pay attention to this feature and the result would be a gasoline vapor smell, just FYI.
Again, observation....
If you rebuild a Carb for your permanent use, I'd strongly recommend using Blue Loctite on all Body and Throttle Screws.

When you perform a "half turn", you turn the screw a quarter of the way around. Is that correct? Should that not be a "quarter turn"?
I adjust the choke plate with a 1/16 drill bit no muss no fuss......Nice Vid!
This was an awesome mini-series of videos, super informative...any guesses to what a mechanic would charge (or should charge) for the same rebuild you just did?
I was curious so I searched for what HIC stands for :

Freaking awesome ! Can't say more! Thank you!
I noticed that both your half-turns were actually quarter turns...
Doesn't that vacuum hose attach to the air cleaner? Old cars used to have a vacuum driven device on the air intake to close off cold air when cold.
What kind of plans do you have for the Fairmont? A V8?
Very good job! I’m an carpet cleaning in Chicago ands I use a power steam machine goes inside the van & needs carb work done I would you do it old machines but it worth

Brand-new and pawn shop don't correlate.
Ok It had the appearance of new and not being used previously. Thank you I stand corrected.
Do you have a video on how to adjust the fast idle cam? I have yet to find a video where anyone actually explains how to adjust it :(. I don't know where to put the adjustment screw on the stepped wheel
Hey Eric,
Why don't you record in 1080p? Is your camera not capable?
Thanks in advance!

you should put an extra fuel filter after the gas tank to longer the age of the main fuel filter you just changed .
great videos thanks.
At 2-9 psi on a non-return system, that non-paper elemented filter should (have) outlast(ed) Eric. Save the money for a new hose.
Most LP fuel filters die by corroding before clogging.
Eric, I believe that the carb would have to be leaned at higher altitudes.
I noticed that too.Yes, it would have to be leaned in higher altitudes. Enriching the mixture would foul out the plugs. You would want less gas in the fuel/air mix.
Hi Erick, great video I have a 1989 Toyota 22r truck, my choke plate dont move when is cold or hot stays at the middle like when is hot, I remove the choke,and even like that the plate dont move, like is stuck somewhere, please help, cheers from Ontario calif.
This looks so much more complex than my motorcycle's carburettor, but I bet this one has a lot more functionality to it with that increased complexity. At least I hope... I really enjoy simple but effective designs, I reckon that is why I am stuck with two 2-stroke motorbikes ;p
Fixing up a carb that's exactly like the one here, do you have any measurements of that small pin that goes in with the bearing ball?
Didn't have any of it in mine either.
You are doing quarter turns when you mean to do half turns :D
You did it Eric!
Hey Eric , Last time i checked my carburettor and cleaned it , it was quite dirty , usually i just put regular 95 octane Unleaded into my tank , is it true that Gasoline additives like Wynn's work at all?
at 14:35 he only turns it a quarter of a turn (90°) and not 180°. And again at 20:40 where he only did 1 and 1/4 ^^
You got a sharp eye as I saw the same thing.
Very cool lesson thanks
EricTheCarGuy do you still think you can mod the fairmont in 2014 or will we have to wait for 2015?
I wish you showed the 'first start' after the re build
Eric please do a vid on a 75 Ford truck 6 cyl. Carter yf. Thanks and God bless.
My one barrel Holley has no tag...lol, ah shucks. I have a 78' Dodge LA318 with a tag-less one barrel as I said Holley, so how how would I go about on that?? The service manual, Ramcharger, yeah, I got one of those lol I think the service manual is worth more than the vehicle, but I digress, the manual goes into great detail on a two barrel....I'm very sure it's a one. Might be good to switch to a fuel injection system...fun!
How about making the new gasket thinner by compressing it (or something like that) instead of using the old one which is almost falling apart?
I was thinking the same thing. Probably wet it with gasoline and compress it. But I could be wrong since I've never worked on a carb
***** No gasoline touches that area- it is a heat activated vacuum valve.
