This Loncin-made generator is fine... even excellent for the money. I prefer it to the Predator 3500 (actually it's the same one but in different colors made by Loncin) due to the better 2 year warranty from Northern Tool.
One issue is the quality of welds on the muffler. They are awful. I think they will rust. I suggest using a high temp muffler spray to paint the muffler so that it doesn't rust through the welds over time, especially if you are close to the water.
I found a service manual for this generator ( [ Ссылка ]).
Some observations:
The fuel filter is behind the back cover (if the cover where you change oil is the front), which is not that easy to take off (DON'T JUST YANK THE BLACK INSERT - IT IS SCREWED IN FROM BEHIND!). If you suspect fuel restriction in the filter, you'll need to remove 6 small black bolts (Philips): 2 at the top under small round rubber covers, 3 on the side of the muffler, one on the side of the battery cover. Then you need to remove three more bolts at the bottom (10mm socket). Finally, take off the wheels. The cover will come off but will be still loosely attached by the pull cord.
I like how they used standard hardware throughout (small Phillips bolts everywhere of the same size, six 10mm head bolts at the bottom and one allen key bolt behind the instrument panel, oh yes don't forget a small Phillips bolt inside the knob).
I have added a short fuel hose, with another fuel filter and a new turn-off valve and brought this new turn-off switch to the front by the air filter box (removed the tank hose from the valve switch, added new hose to the switch and brought it forward with good round bends, added a fuel filter to the existing tank hose, and then added a new turn-off valve - so there is now a new filter and a new turn-off valve before the existing choke/run/turn-off knob. This way, I could run the generator dry when storing it. This addition should be approximately in the same plane (not going down then up), because there is no fuel pump, it's all gravity feed.
The engine on this thing is very similar to the trusty 212cc Powerhorse (or Predator) engine with slight modifications. So, follow the break-in user suggestions for the 212cc engine (change oil after 1 hour - there will be metal dust/sheen). You can use the magnetic dipstick from Atima no. 4322438786. The oil plug is steel: I stuck a small strong magnet to it and the plug will also collect any metal dust in the oil.
The spark plug is Bosch, which is not bad. If you want to go overboard you can put in NGK BPR6EIX iridium plug. It will last for a long time.
Since the wheels are recessed, there is no easy way to replace them with bigger ones. Somebody sells a cool pneumatic wheel kit on ebay for beaucoup bucks. It has machined inserts that go over the axle and move the wheel out from the recess.
I like that the info screen has the hour meter built in. Many generators don't.
