Patents actually make stuff easier to steel. Since they could just change one thing and call it something else. If they don't have one the big companies would basically half to start from scratch. Also they would never steel it anyway since they pretty much want everyone to go efi.

[@snake_eyes_garage]

Not to slag on Edelbrock and Holley but their products are about 10 years behind. So even though they do have EFI solutions they are not sophisticated. And this carb cheater isn't really something they'd be interested in anyways as the EFI systems force you to upgrade everything and are much more profitable. And this market is really small, so the risk of a knock off is fairly low but our Chinese friends can paper-engineer anything, so if they wanted to do it they could. Buy USA (or Australia, Canada, UK).

I think this product is a godsend, there are still a lot of us older "gear heads" that like carbs. Sure EFI is "better" but there is a lot more to go wrong with EFI and it can be expensive to fix IMHO. If I could offer one suggestion, it would be to send a kit to your fellow youtubers, VGG, Junkyard Digs, DD's Speed Shop et al. and get them to install it on one of their "revivals" and have them make a video of the install and results. I think the more people see this being utilized by the other people they watch and hearing the positive feedback (which I am certain you would get) would go a long way in promoting and reassuring people this isn't "snake oil". Just my two cents. Wishing you the best of luck and hope these sell like the proverbial "hot cakes". Keep up the great work.

[@jkalash762]

Got to say, this is pretty nifty for the people new to cars or just carb tuning. Would be an interesting option for a headache free weekend cruiser that isn't efi too. I've been doing the grease on gasket trick my whole life. Dad was born in Tennessee up in the mountains in 1939. When he was growing up it was basically a requirement to keep sheets of gasket making material on hand to keep everything going on the farm. To prolong the gaskets life and help with sealing they would lather them in grease. When times were real tough they even cut out and layered pages of old mail order catalogs and thin cardboard boxes into truly backwoods made gaskets. They would take the layers and brush them in grease and then set them in the sun to get the grease to become thinner. Once it seemed about right they would take thin boards place the greased up stack of paper on it, place another board on top and then back the tractor on top on the boards to compact it all down. If the tractor was what was broken they would press them under the biggest logs they hadn't already split for the smokehouse or wood burner. He told me the gaskets would many times have a small trickle of fluid or vacuum leak initially. Once they were able to get some heat into it a time or two the paper would swell back up and the leaks would be gone. Some of them lasted way longer than they ever should have. 20yrs ago his sister sold their old family tractor which still had several 30+yr old homemade gaskets holding strong. They used all kinds of other materials at times too and another he said worked rather well was leather soaked in grease or pine tar. I've also used permatex 51845 without the activator on carb gaskets and air cleaner base gaskets with a lot of success. Seals great, doesn't really wipe away, and allows the gasket to be reused nearly indefinitely.

[@darthgator639]

Thanks for the tips Luke! I will grease my gaskets where applicable from now on. Will even save me some money in the long run 👍Also a good thing to note is that it is fail safe. When the Carb Cheater box fails, the carburetor will still be able to function.

Suggestion for improvement: For the mid-plate, smoothen, bevel, trumpet or cone the holes on your 3D-model. This way you'll have solid indication which side of the plate needs to face down, and overall better flow and performance on your kit. For the already existing plates, you can mill the underside to resemble a cloverleaf pattern, just round the outside edges, if the middle seems too thin to round off. 5-10 hp more on top of the fuel savings is worth it. Just don't call it "the cloverleaf" to avoid any legal actions.

A fellow Iowa resident! I've taken a recent interest in old Japanese motorcycles, and 4 carbs at once can really frustrate you. I'd love to learn more about how this system works to see if there's a way to make one for a 4 carb/4 cylinder cycle engine.

[@WalterPidgeonsForge]

You may know this already.. but.. for those who don’t.. Typically motorcycles use CV or Constant Velocity carbs.. which respond differently than Holley or Edelbrock designs.. Because they compensate for airflow by raising or lowering the metering rod based on air velocity, you want to balance them using vacuum sticks or airflow meters. You start with them off the bike and use feeler gauges to set the butterflys..do it with them on the idle stop AND at wide open.. you want them exactly in sync with each other… then check with the vacuum sticks or airflow meters.. they will show vacuum leaks or bad valves/valve adjustments, which are common on Japanese bikes because the shim under bucket can be a pain… As a fellow enthusiast of these bikes and Italian and German as well..only a few things kill them.. bad floats and seats, water/ modern fuel left in them causing corrosion .. after that valves sticking and valve springs collapsing from sitting for years. Best of luck and have fun!

[@track1219]

I was into 70s multiple cylinder bikes about 20 years ago. Most of those ( mainly Honda) were not cv carbs. Tiny low speed jets were usually partially plugged up on a neglected bike. Leaky / worn float valves and bad fuel tank petcocks are common. I used a rack of 4 vacuum gages to synchronize them, not hard. High prices for carb parts was the worst problem. Honda (and others )probably had a good reason for using 4 carbs instead of 1, but I don’t know what the reason is. I would love to hear about your efforts to single carb a Japanese multi. Good luck!

[@joshuagies4900]

My buddy and I cleaned/rebuilt the same set of carbs 3-4 times for one motorcycle. Turns out soaking in cleaner is greater than simply spraying with carb cleaner. Also having a tank cleaned/sealed to get rid of the rust/detritus also helps ;-)

[@SteveWyatt]

Id love a break down of how this works. Because this looks like a really cool system.

[@MrXyzasdf]

Modern EFI regulates fuel delivery among other parameters to achieve a consistent and optimal operation curve. Carburetors have a static fuel curve. This device uses a wide band air fuel sensor as feedback with a idle speed regulator to control manifold vacuum, introducing more or less bypass air to achieve optimal operation.

[@erikswensen425]

This looks like an awesome setup for someone who can't afford to go EFI or wants to keep that classic carb but wants something to help hold it in tune better.

[@username-mk8gf]

After seeing him work on the prototype build, I thought it be really fun to make a rudimentary version. Obviously just amping the O2 sensor output into the valve soleniod isn't going to work, but it'd be interesting to see what that does and start from there, maybe then try adding, subtracting or compounding the O2 output with the MAP sensor output... Kind of like a CDI doesn't need to be perfect, it just generally needs to increase the timing with RPM. Some carbs may not need much correction, just to lean out at higher rpm or something

Wideband sensors gave.give the average guy the ability to monitor the A/F ratio real time and not have to rely on the old method of reading spark plugs or having to go to a specialty shop to have tuning done. The easy availability of wideband O2 sensors (and gauges/software to read them) has helped carburated and fuel injected enthusiasts. Anyway nice work!

I did a search, & a company called Thunder Products makes a device for power spots called Dial-a-Jet. It seems like doesn't use any elect feedback....... I'd like to read about that old Holley gizmo!

[@robertwest3093]

I remember the Dial a Jet. Never saw one in action personally but the magazine write ups were always positive.

i have been on the fence on fuel injection. i love the carb but it its very interesting to know how its running

[@Delm21]

Congrats Luke, what a great idea

[@MrAnviljenkins]

It is a simple way to add closed loop fuel mixture control to a carburated system during vehicle conditions where there is a decent amount of manifold vacuum :-). The gear head end user could use this to tweak the carb metering so that this system did not need to adjust as much.

[@MrAnviljenkins]

By simple I mean "simple for the end user" :-).

[@mechanic_prepper]

So a controlled vacuum leak ...simple and effective and what a blessing for folks who live in climates with massive temp and Barometric pressure swings... I fuel inject everything because I lean burn my gas rigs... But this is a decent solution for Holley and Carter that have less than stellar emulsion processes ...good job

I am so waiting for mine to come in the mail. Looking forward to the benchmark video. Great job guys.

Carburetor retrofit Idle air solenoid actuated off of wideband O2 sensor. I like it. Saves a little fuel economy at idle and maintains ideal idle characteristics.

[@ThunderHead289]

It also does quite a bit at cruising, especially low speed- which when I made it I didn't think would work out that way.

[@track1219]

Love the vise grip with rubber hoses trick!

[@pennysgarage]

This is pretty cool. I love this approach to learning how to actually tune a carb using tech 👌

[@ThunderHead289]

You have the right idea 👍

[@225supersix1977]

good idea!!!!......that valve is a 4 wire electric valve, it is a stepper motor bypass, air control valve, it looks like an IAC valve but here we don't just control at idle time , by the MAP sensors and broadband it can be deduced that the air control is at all times, very ingenious, it is similar to the EFI but instead of controlling the cumfuel injection (fuel supply), the carb cheater controls the supply of air, in both ways it is possible to reach stoichiometric mixture control in all engine operating conditions. .......... ...................... that reminds me of 1979 chrysler cars with california emissions controls, even though chrysler was already running the lean burn computer since 1976, the second generation was renamed spark control computer in 1978, chrysler was avoiding meddling with issues of catalyst, which General Motors did quite successfully from 1975, but Chrysler's computer had reached the limit of its emissions control capabilities late at 1978, for 1979 225 slant six engine cars sold in California , more control than usual was required. The computer had a feedback solenoid control module attached to the ignition advance control module, the solenoid did not control the fuel (as was the case with 1981 General Motors' CCC system or Ford's EEC-3), in the case from Chrysler, the solenoid controlled the air, the carburetor was a Holley single barrel, since it was a feedback system, an oxygen sensor was used to work in a closed cycle, the other sensors such as the intake manifold vacuum transducer, throttle position sensor, camshaft sensor, coolant temperature sensor, and others, were already there since 1976, so their signal was only taken from the feedback module (renamed Combustion Computer at 1979). For 1980 all Chrysler V8 Line-up play to Combustion Computer.

It's nice to see a product thats not just glorified tbi.
