The engine ran rough because of 2 things, First, you are automatically running 10% lean because the Alcohol is 10% water, Second, Alcohol requires almost TWICE the mixture ratio of gasoline (7 to 1, instead of 14.6 to 1) for a proper burn. Double the size of the main jet in the carb, and then stand back, you'll get around a 50% horsepower increase, AND, the motor will run very cool, AND, the combustion chamber will be sparkling clean in about 10 minutes of run time. If you want to run it permanently on Isopropyl alcohol you need to get the hottest spark plug that will properly screw into the head, (many automotive plugs will work and are a much higher heat range), then get a belt sander and sand down the cylinder head as much as you dare, to get the compression ratio up... DO NOT bypass the governor or you WILL throw the rod through the side of the crankcase. Always get the motor good and hot each time you run it, or you will start to accumulate water in the oil. If you run it more than around 15 minutes, the moisture in the oil will be boiled out and won't be a problem.

[@ProjectFarm]

All excellent points and advice. Thanks for commenting on how to properly convert an engine to run on rubbing alcohol. Thanks again!

Jim Brown 19 April 2018 3477944124 [e-mail] can you tell me which addative to use to save my 63cc 2stroke engine after a bad possession and no oil mixed in gas. I suspect because of needing help to relocate due to land destruction notice last Friday 13 April 2018. Only 6 weeks. Desperate for the help of land grant and relocation. Blessings

[@DarkLinkAD]

*""The balanced equation is C3H8O + 9/2 O2 = 6 CO2 + 8 H2O, and the molecular weights are C3H8O = 60 g/mol and O2 = 32 g/mol. So, 1 mol * 60 g/m C3H8O : 9/2 mol * 32 g /mol O2, or 60 : 144 or 1 : 2.4. However, air is only 21 % O2 so to get 2.4 g O2 you need 2.4 / 0.21 = 11.4 g air, so the stoichiometric ratio by weight for isopropanol is 11.4 : 1.""* Quote from an Automotive forum 2005. This is likely 100% Isopropyl alcohol. Also note, Ethanol ,Methanol and Isopropyl are different.

I did this back in high school using a Briggs 3hp engine and an electrolux vacuum in blow mode. Ie house from vacs end . I has to also pressurize the gas tank too so gas would not blow back oyt the tank. The boost was in the 2psi range using an electrolux model xxx.

[@TotoGeenen]

Super or turbo charging a carburettor engine is quit hard. You can't just bolt it and and have it work. It might still work but it will run super lean

[@freuderickfrankenstein8417]

First, you need a reliable engine power measurement system in place to measure power gains.

This idea definitely works :)! measuring the hp difference would be cool though.

[@williwonti]

Moonshine is usually less than 60% alcohol so I doubt it would run so good in anything but a low compression tractor from the first half of the last century, but Everclear (95%) should work fine. I second the idea of trying to find the lowest proof that will run a modern small engine. You could add about 5% of distilled water by volume until it stops.

[@brianhind6149]

As usual, great video & I learned something......alcohol burning engines usually have a supply line that is twice the diameter of a gas line, owing to the fact that it requires(so I was led to believe) more alcohol by volume than gasoline to produce the same power. You test seemed not to support that contention. Thanks for your time & trouble......I know you aren't becoming rich making these videos, & the videos are at once , interesting, informative, well thought out, & the effort expended in attempting to eliminate to the degree possible the sources of error that would skew the data & hence the results are without peer.

[@s2upid]

The problem with running piles of nitrous through a 6hp engine is the fact that you're limited on CFM. The engine is physically not pulling in enough air, and whatever HP shot you're running will simply just escape the carb and go into the air. You're also dealing with atomized fuel being near an ignition source (boom). It'll start the mower on fire before it blows the engine.

I have an experiment for you, see if a lawn mower or any other gas motor that runs on gas will run hotter on propane. It is my understanding that it will, but everyone seems to be converting. You don't even need a conversion kit, just a gas line going to the air box with the ability to adjust it. There are actually a lot of videos on here but no one addresses the heat issue.

Zander Xymox best idea since sliced bread

[@07zx14White]

I say mill the heads down as far as operationally possible to get as high of a compression as possible and run some 110 in it, if you can even get the compression high enough to require that much octane.

[@ProjectFarm]

Thank you for this recommendation!

[@barryfields2964]

Kevin Ball just putting a 3&1/2HP head on a 5HP engine will bring up the compression a lot

[@Iexpedite1]

I saw a video of a guy milling a v8 cylinder head using sandpaper on a sheet of glass. The glass surface was flat making home milling possible. If you're going to try it that is how I would achieve a flat sealing surface on the final sanding.

[@07zx14White]

Barry Fields Ok that makes sense. I worked 9 years as a mechanic in the heavy duty industry and I've messed around with mowers and minibikes a descent amount when I was younger but never realized the bolt patterns would match up between the two. Ok so that removes some mystery for me. I'm curious what kind of compression ratio can be had with different heads and milling. Then maybe notch the magneto holes a bit so as to add 5 degrees of advance as well. I'm familiar with small engines decently enough but I've never attempted to build one up. I was just trying to think of cheap methods Mr. Project Farm could do. Thanks for the input.

[@r.j.sworkshop7883]

The problem with the flat head configuration is that when you mill off of the head it lowers the clearance area over the valves until the valves hit the head. It has been a long time since I built go-kart engines but you really couldn't get really high compression (say 12:1) out of a stock head no matter how you modified it.

You always get a thumbs up man!

[@PapiDoesIt]

I ran my riding mower on E-85. Ran like crap.

[@Stacy_Smith]

All They Found Was A Boot Even though it ran like crap, it probably cleaned your engine!* I have run 50/50 E85 & E10 (that CRAP is all they sell in OHIO) just for a fill up and ran it down to "E" on MANY non flex fuel cars. It will run like shit during the 50/50 fill, but will run a lot better on the next fill! Btw, running alcohol CONSTANTLY is BAD for engines! If you live in a state that sells ethanol free gas, SPEND THE EXTRA MONEY FOR IT! * Then again it might not have that much effect on a regular valve setup, but it damn sure will clean injectors!

Maybe the water in it helps ?

[@Doom2pro]

You can remove the water with salt, get close to 99 percent alcohol. Salt dissolves in water not alcohol so it will pull the water out and sink to the bottom, you can then syphon the pure alcohol off the top.

I seen a nos comment. Nitrous just ups the oxygen levels sky high and allows you to burn more gas. This is why a nitrous kit also comes with a gas solenoid. I wouldn't bother with such a test. It's the same concept as a supercharger, but it's not forced. More air/more air.

Propane will make an engine run like it's on gas,just it needs a little fuel/air ratio tweaking,the same goes for ethanol,acetone,natural gas,propane,butane, gas fumes,whatever ignites by a spark. There are millions of cars with a kit installed to run on LPG that will seamlessly turn into gas mode when the LPG runs out or if you press the fuel change button. For testing purposes you can run an engine on propane straightly with a hose on its intake but it will backfire sooner or later and you will need to constantly finding out the fuel air ratio manually for the rpm.

What if you mix 91% isopropyl alcohol and gasoline in a 50/50 ratio?

[@ProjectFarm]

Thank you for this recommendation!

[@themajority5716]

King_Badger_22 I did that in my old go kart as kid... It really helped the acceleration!!!

[@rustycrustymakesstuff6528]

If you do that, you'll have to use a bonding agent such as toluene. We've done this racing karts before and if you don't use something like that it just separates. The problem there is alcohol and gas burn at different rates. Alcohol is basically water based where as gas is obviously oil based. They don't play well together. We always used Pruit racing oil to make the blend. It has the necessary ingredients built into it and was readily available. Pouring alcohol in a gas tank is a pretty good way to get rid of water in you gas tank or fuel filters. It's flammable enough to pass the water.

[@rustycrustymakesstuff6528]

Frank Gutowski I don’t think I said water and alcohol don’t mix. I said alcohol and gas don’t mix. Alcohol and water will definitely mix basically letting the water burn off with the alcohol as long as the ratio of alcohol is high enough. The gas and the alcohol water mixture never integrates but if you can get enough flow to pass the mixture it will burn it off. I am not a chemist and don’t necessarily know exactly how the chemical (thinking it’s toluene but can’t be 100 percent on that) works, but there is something that makes them work together.

[@harlemstrong3054]

Great to see this video. In 2001, I stupidly ran out of fuel in my car. No gas station but a pharmacy nearby. I bought 3 bottles of this 91% rubbing alcohol and was able to drive a few miles to a gas station.

[@ProjectFarm]

Impressive! Glad this worked.

But not to the fuel tank. Dribble the water into the carb while at mid to high rev's intermittently without stalling the engine. Nick.

Run engine on just two stroke mix gas and oil. No four stroke oil

[@ProjectFarm]

Thank you for this recommendation!

[@silentbob267]

I am pretty sure 2 strokes have a method of lubricating the crankshaft/bottom end with the fuel and oil mixture they run on. If you ran a 4 stroke like this on two stoke oil it would lubricate the top of the piston but with no lube in the crank case it would burn up the bearings pretty quick.

[@Chris_Cable]

I used to steal my dads gas from the weed eater for my go-kart a long time ago. It will run fine on 2 stroke gas/oil.

[@silentbob267]

Yeah it will run fine with oil in the crank case, but if you drain the oil and then try to run it I doubt you would make it very far.

[@shatteredbeam]

I've heard you can run a gasoline engine on straight wood gas without any conversion. Might be fun to test.

[@ProjectFarm]

Thank you for this recommendation!

[@barryfields2964]

They are called gasifiers. If you do a search for gasifier you will find many videos

[@radicaldanzero]

I run engines on charcoal gas from homemade charcoal. There is a forum called drive on wood (driveonwood.com) that lots of people are doing just that, running motors and cars on woodgas and charcoalgas.

[@TvshkaHumma]

You can I seen it done on a toyota pickup and it worked pretty well!.

[@madjeepernh6834]

I built a gasifier and did run a pushmower just to try it. Bad filtration gummed up the valves pretty good lol.

[@davisphillips7792]

I knew a guy that ran his 3 wheeler on acetone. Gas on the way to work and would fill it with acetone from our drums for the trip home. Love your videos. You must do a lot of background work as well.

[@ProjectFarm]

Thank you for the feedback

[@elradiuzi]

Try cleaning the crank case with diesel or ATF.

[@ProjectFarm]

Thank you for this recommendation!

[@SassyMudTruckDegenerateDumbFk]

ATF works like a charm. Active Detergents are second to none.

[@rollin18wheels]

Elradiuzi we use ATF to prime the new fuel filters and thoroughly clean the injectors every time we do PM service on our wreckers. Merc/Dex ATF is by far the best diesel fuel system cleaner I have ever seen.

[@maxboonkittypoison]

ATF is a good cleaner ^^

[@Twankiejones]

Yard Sale Dale specifically full metal needle in the carb and bigger jet, that’s the key things mainly if you want it to run well, anything else just help make even more power, been pulling garden tractors for years running alcohol and some nitro to

[@cup_and_cone]

In old cartoons when they would run out of gas they would pour a bottle of moonshine or gin into the gas tank and it would run. Given the widely different proofs, I wonder if there's an ideal ratio to where you wouldn't need to tune the carburetor.

[@ProjectFarm]

Thank you for this recommendation!

[@07zx14White]

thechosendude Have you seen the documentaries of the old school Italian racers? They used to have bottles of grain alcohol stashed along the mountain road course to stop and fill their cars with, and they would always slam a few chugs down to fuel themselves.

[@adamburdette23]

Your videos are perfect for if we run out of gas on the side of the road at night or if there’s just no more gas one day.

[@ProjectFarm]

Thank you!

[@tomg6284]

how about BBQ starting fluid?

[@ProjectFarm]

Thank you for this recommendation!

[@VIDSTORAGE]

That is called NAPTHA Thinner in the labeled cans for paint solvent use,,,it is basically the same thing as charcoal starter ... It is a good additive for fuel to get the fuel injectors and combustion chambers cleaned up but it probably ignites too slow to be used as a pure fuel in a typical gasoline burning engine .

[@DragonBuilds]

I live in the Democratic People's Republic of Kalifornia (DPRK). It's pretty much impossible to buy 90% isopropyl alcohol.

[@ProjectFarm]

lol. Thank you

[@mckenziekeith7434]

I live in California, too. We use 91% at work, so it can't be that hard to get. I think they buy it at a pharmacy (like safeway pharmacy or something).

[@povnw8985]

Alcohol can be distilled to very near 100%. Then you can use a bit of benzene to get the last bit of water out.

[@paulmetz5852]

Always great videos your the only person to do straight up comparing no opinions just facts keep it up brother

[@ProjectFarm]

Thanks, will do!

[@e.b.1652]

You have tried many fuel mixes, what about something that increases oxygen supply ? For example an ozone generator? If I'm not mistaken the oxygen alone is O2, and ozone is O3, can the extra oxygen atom increase performance?

[@ProjectFarm]

Thank you for this recommendation!

[@jussikuusela7345]

Sounds interesting... does an ozone generator produce it in volumes significant for the combustion process? And if it does, will it actually be economical? It needs to draw energy from somewhere. For a stationary engine it is an interesting test. If you intend to boost a vehicle with it, either you need extra batteries or a solar panel etc. for it. Extra weight to carry in addition to the O3 generator means higher fuel consumption. If you use a wind turbine or power it from the vehicle battery, you will add to the fuel consumption just as well. I'm afraid that it would be complicated and cumbersome to the point of being impractical even if it might provide a boost.

[@MrNoodlyone]

O3 is a buck wild oxidant. Almost free radical Oxygen. I've used it in chemical synthesis & it usually just oxidized the crap out of your compound.... Even at -40C. Plus it is a severe irritant & very toxic. It will basically oxidize anything it touches, even you.

[@joshuashea7613]

I agree. I cant wait to see that test!

[@FrankGutowski-ls8jt]

MrNoodlyone It’s used in water treatment for that reason. Indiscriminate oxidant.

[@cameronells4232]

Run a motor on pure sea foam. Like if you wana see.

Project Farm no problem

[@smallmoneysalvia]

I’d like to see an engine get water injection, I remember hearing water sprayed (like a spray bottle) into the carb would blow out carbon deposits and add power.

[@07zx14White]

inertia210 We used to have a guy working for us on roof jobs. We bought him a two stroke scooter so we didn't have to pick him up when we needed him. He showed up one day bragging about filling it with Coleman fuel because he has no money for gas and oil. He made it to the job but the rings and bore we done within a few more days. We bought him gas and oil after he told us what he did but it was too late after his 45 minute inner city morning ride.

[@aeoo371]

inertia210 That might be interesting to see. Thing here is the octane rating is pretty low on "white gas".

[@TheWardog1369]

It would be like pure gasoline without any antiknock compounds or anything. I'd actually be game to see!

[@chriskober1]

Can it run on straight Brake Cleaner?

[@ProjectFarm]

Thank you for this recommendation!

[@gokartbuyer]

Yes you can. It's a dirty trick we used to do for cars that had dead fuel pumps at the dealership. Someone would sit on the radiator support and spray into the intake while someone drove it into the shop. It was better than pushing

[@TNTblow522]
