I've been staring at it a bit today and there is some sort of EGR port in the airbox. It's very close to the carb opening. Thinking maybe I just run a hose from that to inside the throat of the carb. Running propane, the choke should be kept wide open I believe. If I want to run gas, I just pull the hose so it doesn't interfere with the choke. I'm just trying to keep it simple and reversible until the warranty runs out.

just use a us carbs motor snorkel..
they sell just the snorkel for 80-90 bucks.

it places the fuel in the right spot behind the venturi.
cool for under warranty.

that "egr port" might be the crankcase vent!
and do not disable that if it is.

I don't know the ramifications of messing with that hose. You might end up creating a warranty issue that gets denied. The very thing you are trying to avoid.

@chris_5571 I just happened to pull up the manual for the WEN GN875i and noticed that it actually has a manual choke. So, ignore my references to "auto choke".

You could transfer the existing choke mechanism over to the new carb, or just use the manual choke lever at the carb and not hook up the panel choke cable if it is too difficult.

Any updates on a simple carb swap or was it decided the snorkel was the best option at this point? Planning on the same 875i purchase soon and a conversion to NG. Appreciate the information and happy to contribute once I begin.

I have this generator and got the US Carb snorkel to work with Natural gas. Nothing required beyond the typical US Carb instructions. Hope this helps.

Df875ix is dual fuel. 240v.

I have 3 Wen GN 875i generators. Got them before the DF 875ix came out or I probably would’ve purchased those. I only have about 4 hours on each of them but so far they seem to work great. I converted all of them to propane. I don’t have access to NG. I tried 3 different adapters. A motor snorkel , an aluminum venturi donut type and a carburetor from a DF 875ix after it came out shortly after I bought the GNs. For load testing I Tried 4 different regulators , a KN a Cobra , T- 60 and a AHR50-D on each of the adapters and results were surprising. I really thought the aluminum venturi would win hands down. It was extremely disappointing. Only made 5KW on a 7KW running watts machine. The DF carburetor made about 6500 watts on all regulators. The motor snorkel made 6800 watts on 3 of the regulators and on the KN would pull 7KW plus till the breaker tripped. Ended up going with the motor snorkel and the AHR50-D in the end so I can run liquid propane in cold weather and hopefully eliminating the “freezing “ issue. And even though they a not supposed to be parallel capable they are. I paralleled all 3 and put about a 15 KW load on them and they worked perfectly.

Nice! What did you have to do to parallel them?

 

[PBP]

Well. I’m not going to say. I did a very crude “parallel setup just to see if it would work and it did but I wouldn’t recommend it. However you could wire in a proper setup with the safety plugs without too much difficulty. Just make sure to connect all generators first before starting the first one. Then the rest will power up from the outlet side and the hertz will be set so they should be in sync. Guessing that will work on most inverters but could be wrong. If you smoke 1 or both. Not my fault.

Thanks for sharing that.

I ended up buying the GN625i and converting the carb to run NG with a DIY setup for about $40. I use it in 120V only mode and get full rated 5kW out of it.

I suspected that these gennys could be paralleled even though WEN makes no reference to doing so. On the GN625i, there are actually two separate inverters in the inverter housing (the GN875i is similar). One is used for each leg and they can be put in series for 120/240V operation, or paralleled for 120V only operation via the front panel switch. So, it makes sense that adding another similar gen would also be capable of parallel operation. There is not a 120V only switch on the GN875i because the two inverters are connected in series within the inverter housing.

 

[PBP]

Yes. I recall the pictures on that thread. Very nice work. Guess I would not have considered that location. Interesting.

As far as the 120/240 voltage selector i guess I was unaware the 625 had that capability. That’s definitely a nice feature. It would have been nice to have that on the 875 but you are correct it doesn’t. Also both 120v duplex outlets are on one leg and the 30 amp RV outlet is on leg two so yes you’re limited to 3500 running watts per leg. So if you want to balance the load or use more than 3500 watts you will need an adapter for the RV outlet or the 240 outlet. That may or may not be an issue depending on what it’s being used for but not exactly a plus. The only 120v piece of equipment I have that one generator can’t handle is my air compressor. Even running 2 in parallel will make the overload light blink on both briefly.

As far as paralleling goes I was 95 percent sure it would work. And 5 percent sure two brand new generators would end up in a smoking pile of rubble. I videoed it just in case it was a spectacular meltdown but it turned out to be a non event. It worked fine.

...you’re limited to 3500 running watts per leg. So if you want to balance the load or use more than 3500 watts...

That's correct...3500W per leg. Load balancing for an inverter gen is not as important as a conventional gen. You will notice that the 120V RV outlet utilizes only one of the two inverters. So, that is a 100% load imbalance if only using the RV outlet and that is okay. You will also notice that breakers are not used for the two 30A outlets. The inverter(s) electronically control how much current is supplied much better than any breaker can do.

Im glad I didnt buy a powerful generator as didnt think about the extra noise and fuel it would use at the time of buying.... Luckily I bought a 2600watt generator in the end and not a beast, as I will very rarely use over 2000watts saving fuel and noise pollution, but it is a 3100rpm screamer

 

[Dutchy491]

Not everyone can get by with 2600 watts. Me, I need a 240v generator to run my well water pump, which needs about 3500 watts at startup. In a prolonged outage I may run the Honda EM6500 for 2 hours every 12 hours to keep the freezer/fridges cold and run the pump. My Honda eu2200 runs the main fridge, tv and coffee machine etc…
