Review: Update June 2024: Fired it up for the first time in 4 months. It was out of gas so it didn't start. I filled it up with old gas and it started after the 3rd pull. When the fuel lines are primed it usually starts on first pull. ... After 30 min of run time it sputtered. I think the old gas is causing it. I diluted it with good gas, and it seems to work better. Will run a couple of tanks through it to see if it begins operating 100% again. Still looks like a good choice compared against other options even in 2024. The pull cord mechanism was fixed with epoxy and the handle had to be serviced a few times as well because the cord popped out of the handle on quick pulls. I'd probably buy one again if it broke today. Seems like a real workhorse besides the sputtering that is going on, which may be due to old gas. Replacement parts would be nice! Update November 2023: Pull cord recoil assembly partially broke. It still works, but I have to be very careful about how to pull it. No idea where to buy parts. If I can't get replacement parts, this thing will soon be as good as scrap. Still runs otherwise. Update September 2023: Have been happily running mine over a year now. Maybe 500 to 1000 hours on it. Yesterday while running it spilled a whole gallon of gas everywhere. Today I opened it up and found the barb / hose sizing on the tank is INCORRECT. The fuel line is too small for the barb, and overtime (if they didn't fix this on later version of this gen.) the rubber WILL break. ⚠️ You've been warned! ⚠️ -1 star. Still a great generator, but this flaw is dangerous!!! I will replace the hose and continue to use this generator. It has survived 2 heat waves and 1 frozen winter now and keeps chugging. Around -10C it will NOT start. Typical. But if you heat it with a heat source until it thaws a little bit it will start in freezing temps. In temps of 100F it will sputter if it doesn't have sufficient airflow (so this means, don't keep it in a box unless you give it enough air, I kept mine in a generator enclosure which is how I learned this, but out in the open air it runs fine at 100F). Original review June 2022: The Wen 2350 was junk. Kept dying after the break in period. At 1800 watt load, the Wen will go 4 hours on 1 gallon. This larger gen has a bigger engine. It's a tad quieter than the Wen... Probably 2dB. Not too much, but every bit counts. The GM 3300i has more running watt capacity (I haven't tested the limits yet) but it will only run 3 hours on the same 1800 watt load vs the Wen. ... Worth it to me, because I will be stepping the load up to 2900 watts soon, and the Wen generator could never do that. I expect run time to be further reduced on 1 gallon of gas, however, I'm charging large batteries so this means I can charge quicker in a shorter time vs the lower wattage wen Gen.

*by L***N on 3 July 2025*

Delivered on time in good condition. Went thru the change oil twice. 1 hr break in. Fairly simple good instructions. Then loaded it up with two heaters at 3000 watts its stated max. Worked fine no issues. Fairly quiet except for full load. Started up on 2nd pull. I would have like it to have a gas gauge maybe a bigger tank capacity and some gauges but for 460 dollars thats not available. A gas gauge is really short cited on Genmax. Its a five star machine but the gas gauge it loses a star. Also lost 1 star because of the difficulty of getting the spark plug out. There is just no room to get your hand in a pull the wire. Also they supplied 1 oil change but the tiny oil can filled is more oil than the crank case can take. Why not make it so you dump all oil in from the tiny can and the dip stick reads "good". All that I am happy with it.
