Dual Fuel and tri-fuel generator conversion steps for Carburetor Installation (PROPANE or natural gas and gasoline tri-fuel carburetor) for generator, mini bike, and go kart. This video will show you how to convert a generator or other small engine for a tri fuel or dual fuel carb. In the video information is given for a couple types of engines either dual fuel generators or propane for fun. Great alternative to gasoline if you know how to safely use it!
A propane or natural gas engine conversion can be done very quickly, or really any engine so long as you check there are no leaks or issues where the gas can get out with issue.
How do you convert a generator to dual fuel or tri fuel?
1) Get a regulator first and foremost.
2) Get a carburetor.
3) Watch the video for more insight and tips/tricks, but review your engine needs carefully and thoughtfully before beginning.
4) check safety specs on your dual fuel or tri-fuel carburetor from manufacturer specifications. You will want to make sure there are no loose hoses that can get caught up on anything and the proper materials are used.
Once you know how to approach, make sure you install taking your time. You don't want a propane tank dragging around on the ground or in a volatile place! Careful of valve float and be sure you know what it means!
I have a powerhouse generator that can easily be converter to one similar to the champion 3400 dual fuel without more than $50 or less of parts. Pretty nice being able to do that swap to propane easily with a little "how to"! In this video I convert 2 predator engines, and show details on a generator conversion as well. Hopefully it can point you on the right path for your predator generator conversion, champion dual fuel generator or other small engine carburetor conversion needs!

Demo engine used for visuals on dual fuel carb conversion. Mostly same on other generator and engines.

This is one of the few videos that actually helped and answered some questions about this, thanks m8.

Really helpful. Up here in the far NW we get 100 mph winds twice a year. People are always asking me how to convert their gensets to nat gas. Now I can send them to your channel.

Awesome video brotha!

@noahagnew6517 3 года назад

wonderful video, I am tired of my go-kart that is sometimes stored for long periods not starting due to water in the fuel. I wanted to know the difference and potential dangers and you outlined them all very well.

I bought one of these carbs about 4 years ago for my 3.6KW generator that's equipped with a 208 Ducar. 2 pull start every time. 1 pull full choke, then starts next pull at half choke. Never had a problem with it. Handles 83% loads (my testing) just as well as it did on gasoline and the engine runs slightly quieter. I never ran on NG yet. I bet there would be power loss there. For the hose I'm set up for a quick connects from tank to carb. The same hose and quick connects you would use on an air compressor.

I put the same dual carburador un my generator and run perfect, gretings from.chile.

That's a cool test to see that you may lower the hp you gain torque

@russbilzing5348 2 года назад

If I recall, you put half a bottle of octane booster into a half gallon gas tank. You mentioned that the bottle was good for a 29 gallon tank. Didn't you understand that the booster SLOWS down the flame front so that the spark can be set further back, to optimize a longer burn before TDC? Of course the LPG is going to allow the engine to rev higher when you were handicapping the gas burn with the octane booster to the point where it was very likely leaving a heavy deposit on your plug due to the overdose. Without that interference, the LPG could not help but show an improvement.

@kylenavarro9232 2 года назад

Excellent vid! A few questions: 1) Would it be necessary to add some kind of flashback arrestor to prevent backfires from traveling up the fuel line? 2) So the only difference between running NG or propane is the fuel pressure, which is adjusted by that orange knob? 3) Do you really need to get a multi-fuel carburetor for this mod, or could you just do the jerry rig way of making a hole in the intake and feeding the fuel line in that way? It looks like that circular piece on the tri-fuel carb is simply an adjustable regulator for the different fuels, right?

@watahyahknow 2 года назад

have you tried the setup on a scooter / moped engine , i wonder if the rpm chnges and the different loads like when moving up or down a hill will affect the setup

@Comm0ut 2 года назад

LP would require oil injection to use with a two-stroke but a load is a load in any application. A simple carb adapter would be easy to make from scrap if you care to experiment.

@davidsteinfeld9123 10 месяцев назад

I am going to put a hippa branded unit on my piwermate gotta question question for you about how many hours of run time will you get with either a 1lb or a 20 lb bottle of gas Thank you in advance

@marioruben2827 3 года назад

Great vid bro! One question? for a 420cc generator engine this carb kit should work or do I need a different one?

@megoingfast 3 года назад

Different carb. For most it's a gx390 propane, dual fuel, or tri-fuel carb.

@kutubuddinali 2 года назад

This carburettor fit for bike??

@nuttyDesignAndFab 10 месяцев назад

I suspect the reason propane is working better is because it has a higher flame speed; these little engines have a set amount of ignition advance and its not enough for high RPM operation. I wonder how something with an advance key would compare to the propane? 🤔 I suspect the gas engine might make closer top RPM/power but feel more peaky

@mgrasmussonuvc 3 года назад

It should be noted that the governor on a AC generator (with DC converter output) is set to maintain about 60 Cycles Per second output from the generator. On an Inveter generator (DC generator with AC Inverter) the governor is set to respond properly to a load.

@danielauen7790 Год назад

Huh, I wish people made kits like this for the vertical shaft vtwin. maybe Ill just get 2.

@BGWenterprises 2 года назад

Well I now know why the one I got for a wood splitter don't work right. I tried putting lp to the carb before the regulator was on, I must have blown the seal/gasket out. I can start it on gas and get it to run on lp but when it hits a load and bogs the engine the air fuel mix goes WAY bad. Backfires and/or dies. It actually backfires bad enough to move the choke lever from 0 to 100% It's a HF 212cc engine.

@zteshi8017 Год назад

i have a propane mountain bike i love it so much, although i have a stock regulator with a adapter to my 1lb bottle, is that worse?

@stclairstclair 3 года назад

I just scored my neighbors generator, He sold it and had to give the money back because it leaked fuel, For roughly the same price as a carb-rebuild kit and a solenoid I converted it to this, So I have a tri-fuel 5000w generator for a hundred bucks, I couldn't afford this normally.

@papad2948 3 года назад

Interesting, I wonder why duel fuel generators have a lower wattage rating using propane vs gasoline.

@megoingfast 3 года назад

I could guess but since there are so many makes and models it would be that it depends on where the throttle is set. Many generators are set to "full throttle-ish", not always "full potential". Just a guess though.

@electronictim007 2 года назад

The reason is that propane has less BTUs per " unit" than gasoline. Roughly 90% of gas, thus the lower power output. Propane has a much higher octane rating than has so it can handle more compression and timing. An engine built just for LNG has MUCH better performance and fuel consumption.

@biglovesam 3 года назад

So the engine uses the same amount of propane at idle as at full throttle?

@megoingfast 3 года назад

There is a vacuum draw diaphragm (the circle on the bottom of the carb) that opens with flow.

@biglovesam 3 года назад

@@megoingfast quick response. got my propane carb today, no instructions. Hope the diaphragm works properly as you say The choke should never be closed then , it would make a huge vacuum

@MegaKencam 3 года назад

Why do you think RPM is different, since you are running a governor?

@megoingfast 3 года назад

From what I've read up so far and speculate, better fuel air mixture/ratios at that speed. The jetting and eTube for gasoline could likely be tuned some. Not sure in full though.

@MegaKencam 3 года назад

@@megoingfast I doubt it. It's more likely that governor is just not synced to the new carb properly. Like adding a stiffer spring will give you more rpms. I think your testing is very flawed. You need to be testing at the same rpm range.

@megoingfast 3 года назад

@@MegaKencam the governor on the engine tested would not kick in until about 5500+ rpms. Under load, for gasoline, the governor is not reached to limit the throttle position. Both scenarios the engine was allowed to reach potential. Governor should not come into play.

@MegaKencam 3 года назад

@@megoingfast The gov should kick in at 3600 to 3800 rpms. Valve float will kick in around 5000 rpms.

@megoingfast 3 года назад

@@MegaKencam I was wondering if you thought governor kicked in at what the box said for rpm. Based on probability, and having had this conversation many times: I do want to point you to the correct information in a genuine and helpful way but have done this before and would only suggest you join a forum or group on small engines and ask when the governor kicks in versus throttle stop screw setting (which I did accommodate for in the video as I do feel if I did not would not be a valid test as suggested). I mean no snobby reply, but perhaps there is a little more to see about a centrifugal governor rating. I do hope you have a nice day!

DO not crimp your fuel line like this, it is a sure fire way to destroy the fuel line, use or make the proper tool, I use a small pair of needle nose vise grips and have rubber tubing over the jaws so that the sharp edges don't slice into the hose I am crimping, while needle nose pliers will work using a self locking tool will negate the need for a zip tie. Always use rubber tubing on the jaws, save yourself more work or a hard time down the road, nobody wants an engine fire cause you crimped the fuel line and damaged it in a way you can't see only to have it leak fuel all over a hot engine injuring someone or worse. Work smarter not harder.
