How to convert a small gasoline engine to Natural Gas or Propane.

💥💥💥💥 Please Read this !!!BEFORE COMMENTING!!! Very Important!!!💥💥💥💥
This is a proof of concept video ONLY! It is simply to show that a gasoline engine can run on other types of flammable gas. This video is not intended to be a HOW TO guide for a permanent installation generator in an unattended situation. At best it is intended only to show what can be done in an EMERGENCY situation where proper materials are not available.
NOTE 1:
This video used to have captions on the screen that explained a lot of what you are reading here. KZbin got rid of their ANNOTATIONS system and when they did this, it erased all of the informative captions from the video. Please understand this and read this description before commenting.
NOTE 2:
I want to make it clear here that this video is intended to show a very simple way to convert a gasoline engine to natural gas in an Emergency situation. This method, while effective, is not the best way to do this and provides no safety mechanism in case of a fault. Consider this method as a temporary method only to be used in an emergency situation. As this method provides no safety switch to shut off the gas flow in case of motor stoppage, I recommend that this method only be used in an outdoor environment and with continuous supervision. It is not for UNATTENDED USE!
NOTE 3:
This method will only work for gasoline engines that run at a constant speed, such as generators or lawn mowers. In the case of generators, that do run at a constant speed but require more fuel under heavier loads, you may have to adjust the gas flow to where the engine is running a little rich (too much gas) while idling so that there will be enough gas to compensate for the increased demand when the generator is placed under a load.
NOTE 4:
The statements about Obama in this video are about his refusal to repeal the stupid 2007 Clean Air Act passed in 2007 by the Democratic-controlled Congress and signed into law by that moderate turncoat George Bush. The Clean Air Act of 2007 mandated an annual increasing use of ethanol to be mixed with gasoline. In spite of an abundance of scientific evidence proving that the use of ethanol is more harmful to the environment than using plain gasoline, the facts that this law has led to massive deforestation to make more land for corn crops, has caused detrimental food price increases on struggling Americans and food shortages around the world, and is actually very harmful to small engines and older vehicles, Obama continues to cave to the brainless environmentalist and greedy corn lobby and refuses to repeal this harmful legislation.
Disclaimer!
1. This method is to be used only by old fashion true rugged individualist Americans that still have some common sense and believe in personal responsibility. Americans that understand that you are responsible for taking care of yourself and making wise choices and that if you blow yourself or your house up while doing something, that it is your fault and not someone else's fault.
2. This method is not to be used by this new breed of fake Americans that believe that it is everyone else's responsibility to protect them from getting hurt or hurting themselves and that if they get hurt while choosing to do something of their own free will, that someone has to compensate them for it. If you are one of these fake Americans that think this way, please for the love of Pete, do not follow this video!
The Bottom Line.
This method works but provides no safety mechanisms. I use it and have never hurt myself or anyone else. Use at your own risk! Use your own brain and common sense if you choose to use this method. Natural Gas is highly explosive and very dangerous. If you blow yourself up please act like a true American and take responsibility for your own actions and do not call me.

Public Law 110-140, which required the addition of ethanol to gas, was signed by President in Bush in 2007. Just saying.

[@HsCSpanky]

I wouldn't wholly blame ethanol gas for carb problems. Those Tecumseh engines have notoriously horrible carbs. You HAVE to have a quality inline filter in the fuel line and even then, they just clog up. You can clean them as much as you want but you're better off buying a new $30 chinese carb on eBay or doing this conversion. That's the whole reason I'm here, cleaned mine twice and it's still garbage. For a generator that sits, a propane conversion is ideal.

[@EGM210]

What happens when the generator is under a load? It pulls more natural gas or propane. If it pulls more than you are supplying the motor will shut down. With no safety cut off and regulator installed on your gas supply your in for a dangerous situation. It's a dangerous situation you have created. Good luck. Be careful!

[@tomwolff6329]

Lol at "6 months". I call bs.

[@gordonbabcock6136]

You need a valve to shut down fuel flow if the engine should quit running. Gas will still flow making a dangerous situation

[@surferdudedon9249]

Nice informative video. This explains the basics very well and demonstrates how an engine can be run on NG or propane. When you decide to permanently set up an engine for this, you would want the gas to be supplied via a regulator that is made for that purpose since it will change the feed amount based on demand. It responds to venturi vacuum to tailor the flow amount. Otherwise you risk running the engine lean and doing major damage. It doesn't cost a great deal to set this up and anybody living where power outages are too common should consider it. Conversion kits are available for less than $40.

Well folks when you use ethanol you have a mixture of alcohol,gasoline and water,there’s not enough water to affect the way your engine runs but there’s enough to cause the mixture to gel when left to sit in the bowl of the carburetor and jelly won’t go through the jets or gas lines for the ones who don’t know what carburetor jets are but the simple way to solve the problem is to install a gas shut off valve ahead of the carburetor if your machine doesn’t already have one so you can turn off the gas and burn the gas out of the carburetor bowl until the machine stops running. I don’t like ethanol in my car because it affects the gas mileage and can cause fuel system problems in older cars that I prefer.

[@alanblacky9901]

Ethanol doesn't draw in water ethanol has water in it ethanol gasoline also starts to stale within 2 weeks

[@adanmedina2885]

No fancy stuff here.

[@sandybarbee8401]

May I suggest that you ANCHOR that frame to the sidewalk otherwise it'll walk across the yard !!! Running speed varies greatly , from idle to being "under a load" . Have you plugged anything into the generator yet ?

[@readmore3634]

I've read a lot of the comments and one got my attention....when demand is added to "governed" engines the governor adds fuel to compensate....otherwise it will run lean and that can cause overheating. It's best to run engines on the rich side of the scale...it may waste fuel but the cost of rebuilding and engine buys a LOT of NG.

[@wabuminifarm3437]

I just bought a brand new little 2000w 4cycle generator tonight for $150 ,, I was thinking about buying a Tri Fuel conversion kit but they can cost over $300 bucks ,, Two times the price I payed for my little generator,, this is a great way to save money :)

[@hankwilson9202]

Thanks and it is quite helpful to see how to make something out of nothing. I love propane and recall how my farming relatives used propane for cost savings back in the day. we have an immense supply of propane and it should be used and supported more in our society.

[@MrPatdeeee]

Well done. Well said. Wow. The only thing I would do: is to put a "Y" item; in connectors of brass at hardwood stores. And have the Propane AND Natural Gas if one's have it. And be on hand with "On and Off's brass; in each branch of the "Y".

[@michaelknopf6059]

Excellent work. During hurricane Sandy, we couldn't get gasoline but propane was plentiful.

I have a generator exactly like this one except it has a 240 volt twist lock plug and 2) 20 amp 120 VAC outlets instead of 4 of your 120 VAC outlets. It's a little older than yours and still runs fine. I was thinking of converting it to propane years ago when I used to have a 325 gallon propane tank in my yard. I went to a shop that I trusted and asked about it. The owner asked me if it was big enough to serve for what I asked it to do. I said just barely and he advised against converting it because gasoline back then had 115,000 BTU's of energy where propane has 91,600. For general information, gasoline today with ethanol has 120,000 BTU's. He told me that it would devalue the engine horsepower by 20% thereby essentially converting my 5,000 watt generator into a 4,000 watt generator and this was with a proper conversion using a control valve that is analogous to a throttle pump in a car engine. You do need the carburetor in your case for the throttle plate to control air intake. Without the carburetor, your engine would run wild and so would your voltage and frequency until it threw the piston and / or connecting rod out through the oil sump. Also the engine speed / voltage / frequency control governor is also connected to the throttle plate. Another problem with yours and so many other setups here on KZbin is if the engine stalls, the gas will still flow causing a potential explosive situation. Another consideration to think about is if you develop an undetected gas leak, there are 2 carbon brushes and commutator rings, similar to the ones in a car alternator, behind a 1 X 3 inch plastic strip in the middle of the the red back cover of that alternator which energizes the field coil on the rotating shaft of that unit. For as old as you say it is, If the commutator rings have become corroded or if the brushes are well worn, they WILL develop electrical sparks during normal operation that can ignite a gas cloud very easily. In a proper conversion, there is a reverse action regulator that stops gas flow if the engine quits. Most other people don't do these cheap home made conversions because they know it's dangerous. When you load that generator, the governor will open the throttle plate more. In a gasoline fueled situation, it will be demanding / drawing more gas from the carburetor to maintain engine speed keeping the voltage, frequency and amperage of the power level that you demand from it at acceptable levels. With your natural gas conversion, when your wife turns on her blow drier, she will load the generator, the throttle plate will open but there will be NO provision to automatically supply more natural gas to increase engine speed or power like a throttle pump would nor supply enough propane to sustain the demand on the engine thereby causing a lean fuel to air ratio and lugging the fuel starved engine down to a slower speed which will cause the voltage, amperage and AC frequency to drop. This can damage things like refrigeration compressors in fridges, freezers, water coolers and window A/C units and sensitive electronics like flat screen TV's and computers. It can also cause engine knock that you won't hear due to the higher ambient noise from the smaller engine and also cause expensive problems in the engine like potential holes burned in the piston or valve edges to be burned. You can run out and increase gas flow to compensate for the extra load but when she shuts off the blow drier, the engine will flip in the other direction to a rich fuel air mixture simulating a stuck float condition in the liquid gas carburetor, flooding and possibly stalling the engine and there's where the explosive situation that I mentioned comes in with your conversion. The engine stops and the gas flow doesn't. If you are in the shower at this time and don't get out there right away to shut the gas off or restart the engine, the potential problems multiply with every cubic foot of gas released. Also propane is NOT like natural gas. Natural gas is methane which is lighter than air and can float away in an open area. This is why coal miners used to keep canaries in cages and carry them toward the ceiling of the coal mines when they entered. If the bird died, there was what they used to call coal gas, which is also methane, present. Where propane is liquefied petroleum gas, it is heavier than air and will collect close to the floor inside buildings like yours if it happens to flow under the wall next to it seeking lower ground or depressions or low points in the ground outside like flowing water and if the air is still and it should it leak. If someone is walking by such a low point and strikes a match or lighter to light a cigarette, they could potentially ignite a pocket of the gas not even knowing that it's there, if the top of the cloud is below nose level and, again, the air is still. They get killed before they knew it even happened. In 1976, I was in a propane explosion when a machine operator on a road paving crew that I worked on had turned on the wrong valve on a machine and feeding unregulated pressure to the burners that was my job to ignite. There was supposed to be less than 4 pounds of pressure so as to act like a pilot light when lit, but instead, this idiot hit the main feed valve for full pressure operation at 150 pounds. I went to get the igniter and he had invisible gas spewing everywhere. I was a dumb kid back then and didn't know the danger until I found myself standing on a burning candle wick that I had to run across 5 lanes of traffic and a grass center median to escape from. My clothes has absorbed enough propane that most of my body hair had been burned off without even singeing my clothes. The hair on my head got a lot shorter and I couldn't run a comb through it for a month. My left hand and arm suffered 2nd degree burns under a denim jacket sleeve. All in the time that it took me to run across 5 lanes of traffic, about 10 seconds. So, yeah, when it comes to propane or natural gas, I'm a little sensitive about going by the book while handling it. If they didn't have to rush me to the hospital that day, I probably would have pounded the piss out of that machine operator. Good luck with your conversion.

It Works thanks! now I've got to mess with it a bit to get it up to voltage, it just wants to idle but I'm closer to having a working gen set than before I watched your video

[@unagisama5476]

Dang .. classic youtube videos, the nostalgia, very nice .. description alone has solid morals than most content on KZbin these days.

[@waxer12g87]

I've got that exact model genny. Thanks, saved me some time/energy.
