Thanks for great video. I've had a Firman dual fuel for 4 years, fired it up as soon as I got it and a couple of times thereafter...but I stored it with gasoline 😞. I just now tried to start it and it don't start, gas light turns on, turns over and it just don't start. I suspect it is the carb...found your video, thanks for the breakdown. Drained the gas from the genny's tank, put in my truck and diluted it further with 3/4 tank full of premium gas to make sure it don't mess up my truck. Anyways, I took apart the carb and I smelled the fuel in the bowl and it smells kinda of musty/musky...if you know what I mean. I'm gonna clean it like you showed in video. My preferred fuel is propane, I had just put gas to start the genny up when it was new, but I now keep 6 qty (20lb) propane containers for emergencies. I knew better than to store gasoline in tank, but really just lost track of time (Covid really messed up sense of time...haha). Henceforth, I'm gonna do what you recommend in your video (7:11) and let it drain for storage, if I even use gasoline...thanks for the advice. I know long story, but my question is if the genny don't start with gas cuz the carb jets are fowled, etc. ... could I have switched over to propane and would it have started even with a messed up carb? Meaning, does the propane go thru the same carb jets that the gasoline residue clogged up?...I'm just curious.

Awesome!!!!! My problem was the carburetor. Thank you sir.

Enjoy your videos, and your voice is like a step back in time.

Thanks much for the video ! I have a similar dual fuel Firman , and the 'Off' switch within the selector is broken loose and floating around loose. I thought the selector housing was broken! I'll take another look, and with luck, it'll be like yours, a switch.

Great video. I have one of these and js windering if it makes sense to add a fuel filter?

One more comment. It’s important to run the machine under an electric load, to be sure the magnets and copper wires still produce the electrical field for the electricity. More complicated scientifically than that, but hook up a hair dryer or space heater 4 times a year for 5-10 minutes

I like looking it

Ive got one that had a catastrophic incident where the valve was impacted by the piston at least two times, and siezed the motor. Replaced the top end, the motor fires and runs smoothly but under some weird settings that ive discovered. When fuel selector and fuel valve are in the gasoline setting (full right turn) the fuel valve opens however, the fuel solenoid on the bottom of the carb bowl will not activate (pull the pin down) when the fuel selector switch is turned to the gasoline setting. I can hear it click open on the propane setting though... which I suspect is not correct as that would mean both gasoline and propane would be flowing. Somehow the solenoid on off/ for the propane/gasoline settings on teh selector are incorrect. Can the wires just be switched? I ordered a replacement dual fuel module thinking that might also be the culprit but if its just a simple wire/pin in the harness that i need to switch that would make it way easier. I've checked the wiring diagram from the Firman site however all wiring looks to be correct according to that. Wondering if it would be possible for you to caputre a video for me just showing the wire connections that you have on your machine that is working properly, both on the back side of the fuel selctor switch, and also the 12 pin wire connector on the top (dual fuel module) box inside the panel? Any help is appreciated. thanks

So am i right understanding using propane only can effect the carburetor?

Question; so my generator starts and runs for about 3-5 minutes and runs fine with a load on. However, it dies after 5 minutes. It will start back up just fine and run for the exact exact same time and then die. What could this be??

Here's one for you. I have a Firman 7500 Duel fuel. 4/5 years old. Worked fine until I pulled it out of storage this year. Red light comes on for both gas and propane. Starts with either but shuts off after 10 seconds or so. Was stored empty and since it starts, I don't think it's a dirty carb. I checked the oil level and it's fine. Disconnected the wire to the oil level sensor and nothing changed. Shuts off after 10 seconds or so. I checked and cleaned the spark arrestor. Nothing changed. Other that pulling and cleaning the carb (that I'll probably do this weekend)... any suggestions on what to check.

Can you make a video on changing the solenoid

great video but no help. My generator is "new" never ran it for hours in an emergency because no outages,...it is always hard to start but this time finally I checked plug NO SPARK....on a new genny? WTH?? I was hoping there is a reset or something....the plug is totally clean

My generator is running for a few hours then stop it keep doing it and needs more oil 9:42

Easier to buy a new carb and install. Gas is my choice. Swap it out every 6 months and treat with stabilizer fluid. Runs 12 hours plus on a tank. To each his own
