There isn't any reason why it shouldn't work. It's a damn carburetor, it mixes gas and air. Whether it's a lawn mower, motorcycle or V8 car engine. The only thing wrong is a large engine like that needs a little extra gas to help it come off of idle. That's why car carburetors have an ' accelerator pump ' to give an extra squirt when you hit the pedal.

[@ThunderHead289]

@@michaelszczys8316 funny, tell that to the carter carb factory on a 68 f100 240 in-line.

[@tiredironrepair]

I did something like this to my old 96 Ford Escort. The fuel injection computer quit working and I needed to drive to Montana from Vancouver WA to see my youngest son who was moving to Manitoba with his mother. I fabbed a bracket to connect the cable of a Mikuni carb from a CR 250 Honda , clocked it to the throttle where the existing throttle cable was still connected, made a sealing ring to fit in the throttle body of the fuel injection and mounted the carb directly into the throttle body intake without removing any original components. I drove it there and back averaging about 40 mpg. Later by playing with the positions of the throttle body and slide clocking I was getting over 50 mpg and even the check engine light went off and it had more power than it did before even.

Gotta keep the snowblower carb clean and you won’t have issues. They sit most the year and gum up and fill up with crud. It’s usually the venturi tube that runs up the middle of the crab from the fuel bowl to the throat of the carb. It’s a small hole which clogs easily.

[@VochoTalacha]

Here in Mexico people often do this in older V8 engines. They use smaller carbs to try and save a bit on consumption. Yeah, it kills a few horses from the power side, but most times the loss isn't much or enough to be a dealbreaker. EDIT: People use the smaller version of the carb actually used by manufacturers, not actually a tiny one like shown here i.e. in Dodge engines they would take out the 4 barrel carb in their D150 for the 2barrel used in sedans like the 4-door Coronet

[@ocrapo9327]

The engine will probably last longer also

[@HighOverlordSnarffieBeagle]

really, I figured you'd have to crank the amount of fuel going in so that the engine would run properly that the saving in fuel would be so low it wouldn't be worth the trouble, but what do I know I've never tried it

[@rn-rvchronicles]

@@HighOverlordSnarffieBeagle I was thinking the same.

@@HighOverlordSnarffieBeagle the small carb fundamentally can't provide the same amount of fuel. Since it restricts the amount of air it will allow you can't provide as much fuel as it otherwise might take without making the engine horribly rich.

@@DrewLSsix yeah that sounds about right, I'm older but not old enough that I've messed with many carbs, even the first car I owned at 16 had fuel injection, I did at one point had a 77 Lincoln 2 door with a carb and a 460 but when it came time to tune that I let my dad mess with it, I'd just end up making it run worse if I tried

You could install carb pointing backwards too! - *EDIT: Watching the video of Luke driving it, my hypothesis was correct, with such a small throat it really didn't have much for flat spots and therefore didn't need an accelerator pump.*

Car manufacturers are not stupid. They have very talented and bright people working for them. They have always had those type of people's working for them. If a tiny carb quadruple your gas mileage. They would have been up selling them for huge profits. And please do not hit me with some BS conspiracy hypothesis. Chevy don't give a damn about Big Oil they care about their profits.

Sometime later the factory contacted the dealer asking them to get the carburetor back ,and return it to Germany. Well this got the dealership interested in what was going on? The car was recalled and the odd carburetor removed and the correct carb was put in it. The owner was aware what happened too. So the correct carburetor was installed and the owner left the dealership. Weeks later the car was back at the dealership, customers complained about the lower gas mileage the car was getting. Now the carb was back in Germany. My dad never understood how that was possible.

Nice. That’s awesome. I once took two smaller carbs and made a custom manifold for the 5.5 ohv Briggs I had on my old Craftsman mower I put big truck tires on the rear and upped the pulleys a bit to get it to go faster. I made a pedal clutch that tightened the belt when you stepped on it so it engaged the belt and drove. It was pretty cool. You could shift it on the fly.

They pulled a carb off of a briggs lawn mower and mounted it on the engine of the camaro. Shockingly enough, it did run and it actually got excellent milage, BUT, it had absolutely no power.

Too small of a carb for any power. Sure it will idle, but it's not gonna have any acceleration. No matter what you do the engine needs a particular amount of fuel for the air coming in. Not enough fuel and the engine runs hot damaging it very quickly. Might as well put the engine that came with the carb in the car.

@@KevinSmith-os5yz the engine won’t run lean with a smaller carb because the smaller carb is also restricting air and fuel so it will run a normal air fuel mixture just a much less amount of both air and fuel.

[@KevinSmith-os5yz]

Because its not a 302 anymore, it's a 302 with a carb limiting the overall horsepower to around a 100 I would guess. But you still have all the internal friction from the large engine. My minivan gets 33mpg and still has 230hp if needed, but it's computer controlled. This was tried in the 70's, that's why the car builders went with smaller engines and computer controlled fuel injection, carbs can't control the fuel as well. Without any feedback from say an o2 sensor you are always running lean or rich. I used to have a porsche 924, it used mechanical fuel injection with a computer and o2 sensor to adjust fuel mix whole driving. Even then the best it got was 29mpg with a 2.0 liter engine and weighed a lot less.

[@KevinSmith-os5yz]

@@AndrewSosa which means less power, not much different than just not putting your foot so hard on the accelerator. Biggest problem is the friction of the engine itself. Trying to make 4 cylinder power with eight cylinders has twice the friction losses. This was tried back in the 70's without much success. That's why all the 4 cylinders in that era. These days you can get what he is looking for with a good v6 and computer controlled fuel injection. Carbs can't control the fuel mix well enough, no o2 sensor feedback.

i could make thatpart in my back yard with aluminum and my welder. it's not that damn difficult. 3d printing is dumbing down people with mechanical potential . ever buy a 3 d printer? like the price? my way costs virtualy diddle squat. old ass welder and some vision and acquired skills. this sosiety has been relegated to useless consumers of crap made by machines owned by WEALTHY people whom care not about you. again , nice part but it's made of what? mine would last for the life of the equipment. old skool gets it done. every tool in my shop is old and cheap but still accomplishes the task. and reasonably. 3 d printers ....wtf? so go ahead and buy one on credit cause thats the only way you'll get one worth using.

The 3-D printer aspect of the project was just because he wanted to play with his 3-D printer… A scrap of steel plate and some exhaust tubing and you could make this up with a MIG welder in a fraction of the time that printer took and never have to worry about it failing. I’m certainly not knocking him though, he did a really nice job, just saying you don’t need fancy tools to accomplish things, just work with what you have.

What I used to do when I had a carburetor years ago to double my mileage is add a very small amount of vacuum to one of the vents on the carb, has to be the right amount, very simple and easy way to double mileage. Must be the right vent or the car won’t start, must be vacuum that drops when you step on the gas so you have full power and get good mileage. I’ll never have a carb again but it was fun at that time.

[@tomato1417]

How would one choose the optimal vent to apply vacuum to?

[@justanotherday1974]

@@tomato1417 it will only work on 1 vent, if the wrong one then it won’t work. Some cars only have one vent, so it’s easy, if 2 then choose one and start the car and then shut off and start again, if the car won’t start then you have the wrong one. It just a very small amount of vacuum, just enough that your finger will barely suck to the hose, use a valve to adjust to the right amount, too much and the car won’t run, too little and you won’t double your mileage.

They tried to send him the van to his address in the USA, but it was refused. It got 80mpg and the US only allowed 22 at the time. They said they could ship it to as close as possible in another country, and he could ship it the rest of the way himself, THEY just couldn't ship it into the USA. Remember the 1st ship of Priuses that had to be turned around and DE-engineered from over 80mpg down to 65. Ask any old Toyota dealer.

[@zymmer4]

By the physical properties of the float level vs bowl pressure vs float level..I am predicting that with a very low float level that the carb will act like a fuel injection nozzle with a needle jet..lol..at throttle, my guess is that the float needle jet will stay open and that the engine will just be sucking fuel at the rate the regulator is set at..which makes me want to experiment with "over jet pressure" senerios..whereby at throttle, the fuel pressure may be upped to 7 or 8 pounds..over charging the needle..but testing will give an idle..and at higher engine speeds, 8 psi fuel pressure just dumping into the intake.🤩

Still if a very functional manifold can be created for 2 spread bore 4 barrel carbs with progressive linkage, why not 4 2barrels with long tube individual runners to each intake valve.

@@unknownsoul13 you’re essentially just running a convoluted four barrel then. This experiment is fun to watch but is just a flow test.

Hot rodders then started putting more carbs on prior to four barrel carbs because you need more air and more fuel to make more power.
