Our take on the Black 15HP Gas Engine 420cc, OHV 4-Stroke Single Cylinder 8800W Motor with 6.5L Tank

This is a 420cc air-cooled, 4-stroke gasoline engine rated at 15 HP and 8,800W, with a 6.5L fuel tank and pull start. It is a generic, unbranded engine intended as a replacement or power source for equipment like go-karts, pressure washers, generators, and log splitters. It competes on displacement and output with established engines such as the Honda GX390 and Predator 420cc, but it lacks a known brand, dealer network, and published torque curve. Buyers should expect to verify the mounting pattern and shaft size before ordering.

Pros
  • Large 420cc displacement for strong torque at low RPM
  • Air-cooled and simple pull-start design with few electronics
  • 6.5L tank gives long run times between refuels
  • Common 4-stroke layout that many small-engine mechanics can service
  • Light enough at about 59 lbs for one-person installation
Cons
  • Unbranded, so parts and warranty support are uncertain
  • No electric start; pull start only
  • No published torque or fuel-consumption curve to compare with name brands
  • Requires initial oil change and regular maintenance that some buyers overlook
  • Mounting and shaft dimensions are not standardized across all applications

Questions and answers

Will this fit my go-kart or pressure washer?
Fit depends on the mounting bolt pattern and shaft size, which are not standardized. Measure your existing engine's base and shaft before ordering. The engine is 17.1 inches long and 17.7 inches high, so check clearance as well.
Does it come with oil and fuel?
No fuel is included, and the engine ships without oil. You must add engine oil before the first start. The manual lists a 1.1L oil capacity.
How often should I change the oil?
Change the oil after the first 10 hours of use, then every 100 hours. This is critical for longevity, especially on a new engine.
Is it really 15 HP?
The listing rates it at 15 HP and 8,800W, but actual output can vary. Without a published torque curve, treat the rating as approximate. Many 420cc engines produce around 13-14 HP in real-world use.
What is included in the box?
You get the engine, an English manual, and all accessories needed for installation. No fuel, oil, or battery is included.
