Good video, but it's worth mentioning to be careful not to cross thread the propane/nat. Gas hookup. You can also add a quick connect that makes hookup alot easier for most. Just thought I'd mention it. Great job.
Hope You will respond (know this is an old post): I have the exact same gen as you. Mine is near new but sat too long and Ethanol smoked the carb. I have rebuilt the carb and gen is running perfectly on gasoline now. I ordered the same carb (via the link) as you and also a regulator for my propane bottle but from a generator supply place that claimed it was better than a BBQ regulator and could handle a higher flow rate. All that said, I want to know if you were able to get your gen to run as smooth off of Propane as on gasoline. Another viewer commented it was not running too smooth in the video and I agree that it wasn't as well and wanted to know how you smoothed it out if you did. I found several version of the carb I purchased (identical to yours) and they have a screw adjustment between the top of the carb mounted regulator and the carb at the base of the black propane supply hose. I was wondering if that is an improvement to help tune the carb to the engine while on propane. (??) Any help would be appreciated. Thanks for the great two vids!!
@@shawnmrfixitlee6478 Really look forward to the new post. Is the adjustable regulator you mention the one on the propane bottle or on the carb? Thanks again!
I have an 8750 Watt 7000 run I believe Harbor Freight predator generator. Supposedly that engine is 13 horsepower. But the wattage of this carburetor if I remember right is rated for 5000 Watts. I wonder if this carburetor will work for me? Also maybe you know if that predator generator is brushed or brushless? You sound like you know more about these than I do... Thanks
I think it is 420cc www.harborfreight.com/8750-Max-Starting7000-Running-Watts-13-HP-420cc-Generator-EPA-III-with-GFCI-Outlet-Protection-63085.html?ccdenc=eyJjb2RlIjoiNTA0MTIzODUiLCJza3UiOiI2MzA4NSIsImlzIjoiNTM5Ljk5IiwicHJvZHVjdF9p%0D%0AZCI6IjExODEzIn0%3D%0D%0A
Great video! So, does it means that if you run the LP gas after gasoline, will the carburetor stay clean?? I’m wondering if by running the LP gas will burn all the gasoline left in the carburetor!?! Thanks
The tri-fuel carb I bought has a drain for the gas in the float bowl. Most carbs have a drain screw at the bottom of the float bowl. Either way, to drain the fuel just turn off the gas and let the generator burn it off.
Thank you very much for this video. I would like to ask you a question. Is the operating capacity of the amps the same if the engine is running on gasoline or is there a difference I have tested? It turns out that the engine works at half capacity if it is run on liquefied gas or is there a malfunction? I would like to try a test about the load and run it on the same generator with liquefied petroleum gas
Hello, I recently converted a small Predator 422cc engine used to power a generator from gasoline to tri-fuel (NG/Propane/Gasoline). I am concerned about valve issues, in that from what I understand, valves for a gasoline fueled engine are not as durable as those for natural gas and propane powered engines. Apparently this can cause heat and lubrication issues with converted engines, as well as "valve recession". As you are small engine specialist, I would appreciate any guidance you may be able to give on this issue. If possible, would like to know of any experience you may have had with converted engines, and how much and to what degree the conversion affected their over all life. Also, I would like to research compatible hardened valves and or heads for this engine, for which I hear may be a "clone" of a Honda model. I thank you in advance and would appreciate any input.
@@shawnmrfixitlee6478 thanks. If you could, was your engine converted from gasoline to natural gas? How long have you been running it and have you ran it for a longer time, or just in short burst. Also, are you saying that LPG has more oil in it than gasoline. Thanks again.
not sure . But if it is like this one it is just a solenoid to cut off the fuel to the main jet when you shut off the engine . They plug in where the old carb did . Thanks !
I have a Generac gp6500e electric start, I have a propane carb where do the 2 solenoid wires connect. The generator carb did not have a fuel solenoid shut off so no wires to hook them to. Do I even need them?
When the engine is cut off does the propane keep going into the carburetor or is there some kind of valve that only lets gas come out when engine is running?
this one will fit but you will have to mod your air cleaner a bit . They don't make one for the vacuum chock setup like you have . thanks !! www.ebay.com/itm/New-Carburetor-Dual-Fuel-Propane-Gasoline-Fit-Honda-GX340-GX390-GX420-188F-190F/312899541355?epid=1001040860&hash=item48da44196b:g:iw4AAOSwqQpd11qi

If you use quick connects make sure they are full bore... not the ones with the small holes in the fittings
Nice kit and a great install Shawn.
Interesting how that works; Shawn have a great father's day..

you will need a adjustable regulator , I found this out after making this vid , i will post an update soon !!
@@shawnmrfixitlee6478 Really look forward to the new post. Is the adjustable regulator you mention the one on the propane bottle or on the carb? Thanks again!
How long do you think it will run on a tank of propane? Are you going to run it on natural gas?
It will run about the same on propane time wise , About 10 hours .. I have no natural gas to hook it to or I would do that for sure .. Thanks Harold !
I just got a westinghouse 7500 watt genset im def going to do this thanks for the video !!!
AWESOME , Thanks !!
Great video very easy to understand Thanks
ThankYou !
Are you going yo do a Natural Gas test also?
no, But I would if I had natural gas service here . Thanks !
when your propane tank gets low on fuel,does the motor staraat to stall?
No it runs fine till it's empty. Thanks !

if it's a 390cc engine it will work fine .. What model is the gen set ??
I think it is 420cc

Hello,thank you for such an informative video. Can that conversion kit also run on Bio-gas?
I don't know . It is made for LP or NG ! Thanks..
Thank you Sir.
Great video! So, does it means that if you run the LP gas after gasoline, will the carburetor stay clean?? I’m wondering if by running the LP gas will burn all the gasoline left in the carburetor!?!

never thought of that , I think it would ! Thanks..

there should be no difference if everything is working right .

I have never had any valve issues with LPG , It does have more oil in it than gasoline does . Thanks !

hello, good work.
On my lpg carburettor are 2 Kabel ...what is it for?
best wishes from Germany.
not sure . But if it is like this one it is just a solenoid
to cut off the fuel to the main jet when you shut off the engine . They plug in where the old carb did . Thanks !
In the first video, you removed a piece .. you didn't use it .. what's that used for?
I have a Generac gp6500e electric start, I have a propane carb where do the 2 solenoid wires connect. The generator carb did not have a fuel solenoid shut off so no wires to hook them to. Do I even need them?
I found mine will run with or without them. Thanks !
Is it correct that the solenoid wires do not have polarity and it does not matter how they are connected? Both wires are the same color.
Does not matter on those. Just plug them in ! Thanks..
👍 Danke fürs Hochladen!
👍 Thanks for uploading!
👍 Very good and beautiful, thank you!
👍 Sehr gut und schön, danke!
How long does the generator run on a regular size tank of Propane ?
Not sure , I have never run it threw a full tank at one time !! Thanks ..
Pretty cool.
Thanks George !!
When the engine is cut off does the propane keep going into the carburetor or is there some kind of valve that only lets gas come out when engine is running?
No it cuts the fuel off , thanks !
@@shawnmrfixitlee6478 how does it shut the gas off, by a solenoid?
@@northgeorgia7357 no , the regulator shuts down when there is no demand from the engine . No vacuum that is .. Thanks !
Cool
Hi, where did you hook up those two cables from the solenoid on the bottom of your carb?
They just plug back in where the old carb did ! Thanks
Shawn, I looked at the eBay page, can you tell me which part runs the Honda Power Boss 7000 watt generator? I can’t tell
this one will fit but you will have to mod your air cleaner a bit . They don't make one for the vacuum chock setup like you have . thanks !!

ShawnMrFixitlee - Hi Shawn, thanks for the reply. That one looks like it won’t run natural gas. That’s what I’m looking for. Am I out of luck?
@@Pithiny Ahh, You might be . I can't find one for natural gas .
Where it available
I got mine on Ebay , Thanks !
Do you have a link for the hose and regulator?
sorry I don't . It's been to long ago , Thanks !
Here are two options through Amazon depending on your tank. Just copy/paste the number into the Amazon search bar.
B07L9FC9NS
B000WB2BH2
Where's the link to where you purchased the conversion kit?
link is in part 1
what does the rpm read to keep your engine speed to keep at 60 cycles and proper voltage...just saying
3600 rpm
