Can I use synthetic lubricating oil instead of mineral oil?
It is highly recommended to use synthetic lubricating oil, especially fully synthetic oil, because it not only improves engine performance but also helps prevent carbon buildup on the piston.
Have the DLE engines been run and tuned before shipping?
All key components of DLE engines are tested before leaving the factory, such as the ignition, carburetor, etc., but the engine itself is not run in.
There are three wires on the ignition, all with female connectors. There are two black plugs and one red plug; if the red plug is meant for the battery, what is the purpose of the other two plugs?
The ignition of each DLE engine has three wires: the red plug connects to the battery, the plug with black oil on the surface connects to the sensor, and the other one connects to the tachometer output. The wire that contacts the tachometer cannot contact the sensor.
Some carburetors have two tubes, which one is connected to the fuel tank?
The black nipple is the fuel inlet and the brass nozzle is the air inlet, they can make the air pressure maintain balance in the carburetor.
What is the ignition voltage? Can I use a lithium battery?
Ignition voltage: 4.8-8.4 V, max voltage: 9 V
Does DLE offer after-sales warranty service? How long is the warranty?
All DLE engines come with a one-year warranty. If they don't work the first time they're used, we will replace it with a new one for the customer. If the engine can't start due to quality issues, we will provide components to the dealers and the dealers will repair it.
