Generac 4000XL GN-220 Generator - Will It Run? 

Loving the drone footage mate

Bought a Chinese carburetor for 28.00 shipped and it works good. Ordered the kit with it. My 4000XL was bought in the 90s and used in plumbing and repair of new homes and old homes.

Thanks for the video. The wild frequency readings were likely caused by dirty power (lots of spikes in the sine wave) and it's fooling the multimeter into thinking that it's running faster than it actually is. To check the frequency if you can't trust the Hz reading, use an inductive-type engine tachometer (one that runs a wire around the spark plug HV wire) to validate that the engine is indeed at or near 3600 RPM. I target between 3660-3720 RPM or 61-62Hz, unloaded. Assuming the governor is tuned correctly, the generator should sit around 60Hz once you apply some load.

Our maintenance guy gave me one of these, but its the electric start version. Your video has been very helpful thanks!

Nice little project. I just got one in a equipment bundle I bought.

I can watch your videos all day. I feel I could take apart a carb and clean it... probably not😂

Nagano (Japanese Company with a good rep) made all these engines on this briggs and generac joint venture. GN stands for Generac Nagano. Briggs was in charge of all except the engine that was Generac's responsibly and they contracted Nagano.

I'll bet the probes on the meter stuck in the outlet were causing fluctuations in the sine wave from vibration. Try taking a reading with a kill a watt meter that plugs in. I have this same gen, and it was revving high like a runaway, but I found out that the carb was shot and mixture was sketchy. A new carb $20 on Amazon and shes like new. Thanks for the video!

Thep tail are for battery charging cable

Beer is the best type of payment. As far as I knew, Generac manufactures their own engines. And I even think those OHVI (Industrial) are American made. That looks like a mid 90s machine, before they switched to their orange scheme. But I'm just a hack so am more than likely wrong 🤣

The engines on the Briggs and Stratton generators look fairly similar to the one on the Generac. But it is possible that it could just be some Chinese clone of the Briggs like on the newer ones.

Awesome video Sir. Cheers! 🦅

Hey, thank you for your quick response is the same generator you you have in your video Generac 4000LX OK one issue is I’m having a trouble time getting the carburetor adjusted and also the bottom outlet doesn’t put out any voltage

I ended up inheriting one of these…same exact model. Still in the plastic wrapper, engine never run, like a time capsule. Perfect brand new condition yet 20+ years old. Wondering what to do with it.

Nice fix chris 👍👏🔧

Generac makes a special cable that uses that odd plug. It is used for 12 volt equipment or battery charging. It's hard to find and they usually end up getting lost 99% of the time

Generac was bought by briggs and stratton so it's a briggs

At least you were able to get the start and die without starting fuild or carb spray

I hve one of thease it wont spacrk unless you unplug the conecter right behind the carb do you know wht could be causing that

WHERE IS THE OIL DRAIN PLUG

Nice Vid!

Ok then good one Mate

Hey bud, I need to reach out to you. I need help troubleshooting my generator.
