Save Big $$ With This Easy Conversion! 

You lose around 10% of maximum power on propane and another 10% on natural gas, roughly, assuming your motor is matched to the gen head. If the motor is oversized then you might not lose as much or any. For example, you need around 10 hp for a 5kw gen but on NG your 10 hp motor is now an 8 hp motor so now you have a 4kw gen. If your 5kw gen comes with an oversized 12 hp motor (most don't) then you wouldn't lose anything.

I'm surprised he didn't mention it, it is considerably less

I dunno. He's unwrapping a lot of 'Space Shuttle' parts in the beeginnin'. : /

Yeah he needs to read the manual, everybody knows the Red wire goes to the Sparkplug. That where the wheel get's power from.

​@@MitchEllis-e4y TD does mention 1.Orfice, 2.Elbows, 3.Nipples, 4.Gas and probably more not picked up. TD is a stallion repairman to bad he is shutting down the business but completely understandable. Howlin' Wolf & Eric Clapton would be proud of TD learing from "Back Mower Man"😂

And...when it gets cold (-30 C or worse)...NG won't freeze up on you like 20lb bottles of propane. Don't remember the old 1000gallon tank freezing up, but few people running those anymore due to cost of propane vs NG.

Yeah, it was flipped 180 in x and y and he only flipped it back in x.

10 % - 20 % loss in power/output.

And with natural gas the generator will be down even more on the wattage.

@@dandearman2871 Yup 10% less on NG versus LP.

It depends on the engine. Newer overhead valve engines have higher compression ratios than the old school flathead engines and don't lose as much power on LP versus gas. However it is 5-8% less, and that's mostly because in order to run the most efficiently on LP gas, the compression ratio needs to be slightly higher, as well as more spark advance. LP gas has an equivalent octane rating of about 110, so it burns slower, and needs more time to get the fire going, so that's the reason for more degrees of advance. You need to fire that spark plug well in advance of the piston reaching TDC, or the main reason you're losing power is you're sending unburned propane right out the exhaust, it didn't have enough time to complete combustion. It's also more resistant to detonation, so you can increase the compression ratio. There is a point of rapidly diminishing returns however, because without some sort of forced induction like a turbocharger, increasing the compression ratio increases the pumping losses of the engine, plus increases the stress on the internals. Very high compression engines come with very heavy pistons and rods etc like a diesel engine, so with a small engine like this you can't go crazy with the compression ratio or you might pop the cheap head gasket or stretch the head bolts, these small engines aren't built like a nascar engine... lol

btu to kwh calculator will tell you fuel consumption

Just a rough estimate I'd think you would get the equivalent of 3.5 g of gasoline from that 20 pounder.

Where I live propane refills are around $4/gal at U-Haul ($17 for a #20 tank) and propane has around 80% of the energy so it works out to around $5/gallon gasoline equivalent. Could be more (if you do the tank swap thing at the grocery store where they only give you 15 lbs.) or less in some parts of the country - some guy in TX told me that he pays $12 for a fill. $5/gal sounds high but if you are using this for emergency backup and only going thru a tank or two, paying a couple of bucks extra is nothing compared with having the gen start and not having to deal with dirty carburetors.

@@throwbo I like the storability of propane. You could get bigger tanks like the ones RV's use as well. Give you some more run time and you can still move them around without much trouble.

@@throwbo Thanks for the info. Having to deal with clogged carbs and stale fuel is a huge pain.👍

Internal threads are left handed, external are right handed

The old fashioned left hand threaded stuff is still used, even on brand new propane regulators for things like grills and heaters. The right hand square fittings are used on propane powered motive equipment like forklifts. That's why propane tanks have both types of connectors.

I asked the salesman at Century that question when I bought my kit. So how long your unit runs on a gallon of gas would be abought the same for a gallon of propane. A 20# LP tank is not quite 5 gallons. So you can do the math if you know that gasoline/ hr rate for your unit.

to change the timming on any combustion motor with out changing the flywheel or distrbutor is to change the spark plug gap like he did.

Was thinking must be a timing issue. 😅

Electric start has nothing to do with the timing. On gens, it doesn't seem like propane changes the timing enough for you to need to change the flywheel. You can get offset woodruff keys so you don't have to actually change the whole flywheel to advance the spark. Some ppl say you should reduce the spark gap by about 25%, so if you are running 0.030 then down to 0.023.

I imagine fabing an offset plate to mount the coil might work too. Cheaper than the flywheel, and no sacrificing strength in the shaft key.

Awesome idea! :)

@@warrenvalentino5763 the interlock switch for the panel is much cheaper than a transfer box. My genny isnt big enough to power the entire house so I just switch off all the breakers and then switch on the rooms I want to run, pretty cool!

@@masterofnonetv8361 =>That's exactly what I have. A large generator only sucks up a lot more fuel just running at an idle and that's the last thing I want after a hurricane is to have to go out & look for propane or gasoline. I only run my generator an night to power our window AC & refrigerator and then during the day for a while to keep the refrigerator cold.

I have the interlock on the breaker panel too, super cheap. My Diesel powers the whole house including central AC.

bidens plan is to sell all propane to China

It would look nice but you'd be giving up the ability to use gasoline in an emergency.

Yes it can be removed completely if you never plan to use gasoline in your generator again but why not keep it in case you can't get propane right away 🤔? Gas stations are everywhere unlike propane.

🎶"You can get most anything you want, at Alice's Restaurant!" 🎶 Except Alice.....maybe.....🤔🙄😁

If it's electric start, yes, but the alternator may not make enough electricity to power them to a useful brightness. Also, you'd probably be sacrificing charging the battery in the process. The alternator might be swapped-out with a higher-output unit, but more engine power used to make electricity is less available to spin the blade. If it's pull start only, you'd need to add an alternator, which is a stator, new flywheel and probably some sort of regulator/rectifier (which may or may not be included with the stator). The flywheel should be a straight swap, but there's a good chance the engine will need modification to mount the stator. A rectifier should just tuck under the flywheel while a regulator is easily mounted just about anywhere. Finally, incandescent lights are pretty agnostic and forgiving about the electricity you feed them, so long as the voltage is relatively close to rated. However, they use 7-10x the power as LEDs for the same light output. LED's on the other hand, depending on the support circuitry running them, may require DC only at a pretty consistent and stable voltage. I wouldn't run LEDs with just a rectifier unless the support circuitry was specifically designed to handle the output. Of course, there's always just slapping some battery-powered/rechargeable lights on it.

@@ItsMrAssholeToYou ty for the response 👍

I bought a headband light at Walmart for $7.99, works great for push mowing after dark.

YES THis is a great thing

Vapor fuel doesn't need choke or warmup time. Just need to get the vapor into the cylinder and it'll go.

Update: Still not leaking. It ain't the space shuttle 😂 Thanks fer watchin' partner

Maybe I was a bit harsh but when you not apply to about 1/3 to 1/2 the circumference of the threads you have to count in a smaller amount of thread sealant on the threads sealing the leak. And, as for me and my luck Mr Murphy of Murphy’s laws knows everything about me and everything I do. I’m pretty sure had that been me doing it that way you could have heard the sumbeach laughing at me like yeah right that’s gonna work ha ha in the background. Good job fellow hillbilly.

Not quite sure what you meant at the end there, but one of the cool things about propane is that it's not like gas where there is fuel in the bowl after you close the fuel valve so the gen keeps running for several minutes. When you close the valve on the propane tank the gen stops instantly.

@@throwbo what planet are you from, after you shut valve there's still propane in the lines which allows it to keep running until all the propane is used up.

@@Mazel_Tov_888 Have you actually tried this? Even if there is propane in the line once you close the valve it loses pressure and can no longer come out. If you actually had a propane generator you would see that it dies almost instantly. Even if you don't have a gen, try this on your gas grill (if you have one of those) and let me know how long the flame burns after you shut the tank valve.

@@throwbo Yes, I've done it with my dual fuel gen. That's why I'm saying what I'm saying. When you close the valve, the line is still pressurized and still has propane in it. Same as when you shut the petcock, the line is still pressurized and fuel is still in the line. It runs until the fuel is burnt up.

@@Mazel_Tov_888 A carb has a bowl with liquid fuel and one carb bowl full of liquid gasoline equals a bunch of gas vapor. Gases are very light so one lineful of propane is not nearly as much. My results may be skewed because I have one of those Chinese dual fuel carbs where the demand regulator is the size of the palm of your hand. Maybe a bigger full sized Garretson holds more gas. The regulator has a diaphragm and will act like a bellows and store a little bit of gas under pressure. It's not unlike the vacuum reservoir on your power brakes which stores enough vacuum for you to pump the brakes a couple of times.

I was wondering about that as well.

Yep ! Always best to be safe in case something goes wrong.

I did a conversion using this kit 10yrs ago and the instructions I had stated to turn off at the bottle not to use the engine off switch.

When not in use, yes you do want to turn off the gas at the tank (fuel source). However, these systems are touted to be "on-demand" setups - the gas will not flow unless engine vacuum is drawing it in, hence the reason for the purge/primer button to initiate flow of gas into the engine intake to get the motor started.

@@killer2600 I know that am not stupid, am just saying what it says in the instructions.

Personally I enjoy inhaling it

Was it a small tank? normally they only freeze if you are over drawing the tank not because of temperature. When it’s cold out the small tank will not produce gas as fast as the equipment is using it.

Can’t tell if you’re kidding, but that’s silly.

Or what my dad does is he has a little gated area to keep it out of the wind, and just point the exhaust and hot air from the generator at the tank. Not right up against it obviously but like a foot or so away, then that hot air keeps the tank warm enough to compensate for the chilling effect of vapor withdrawal

I would like to know that also!

Sorry i won’t ever do that again. Next time I’ll check with you first . 😂

​@@TarylFixesAllYou must also have a "load block" adjuster to change from propane to NG, and back again.

​@@TarylFixesAllThe "power valve" adjuster IS the "load block". 😉

​@@TarylFixesAllThat IS a model "KN" regulator. It's the same as my new one. Just in case you need parts for it some day.

No I looked back and I don't recognize it. Looks like a small axe head or a wedge.

@@brnmcc01 Only recognized it because I had a package of white ones- they are nylon flail blades for straight shaft brush cutters. I chuckled seeing it on that comedic diagnostic wheel, because I had just got my own trimmer out days earlier and installed new ones.

@@marvinheemeyer9768 Oh ok, never used one before. Cool.

@samtate1260 What does fog mean in this context?

@@BryanPAllenlikely he is referring to using fogging oil to coat the inside of the carb, valves and cylinder.

@@akbychoice thanks for the explanation. I’ve never heard of that.
