6, see whether the power is reasonable. The power index directly indicates the working capacity of gasoline engine, and the work capacity is limited by the size and displacement of its cylinder. When the cylinder size and its displacement are constant, the maximum power output will be fixed, even if there is a deviation, it will not be too large, usually no more than 10%.
Two, look at the safety protection and warning of the whole machine
The safety protection devices and warning signs can effectively guarantee the personal safety of the users. They belong to the national mandatory standard. Whether they meet the requirements is one of the important ways to judge the fake and shoddy small gasoline engines.

3. See if the fuel tank of a small gasoline engine is equipped with a warning sign to prevent fire risk.
Three. Look at the quality of assembly and appearance
1. Look at the material. Check whether the thickness of the sheet covered is consistent, whether the surface is smooth and smooth, or whether the waste material is made. See whether the frame, protective cover and other parts are due to the deion of the material too thin, the whole machine has no distortion.
2, look at the quality of the paint. Check the paint surface inside and outside the machine is uniform, smooth, consistent color, there are no wrinkles, peeling, flow, lacquer and other defects. Paint the inner surface with a sharp object to check if there is a primer.
3. See the quality of welding. Check the frame and hood part is durable, weld is uniform, there is no leaking welding, weld, wear, sealing off phenomenon.
4. Look at the quality of assembly. Check all parts are complete, easy to scratch parts without flash and burr, installation is firm; the flywheel nut or the power output shaft is to take effective measures in all nuts, rotation and transmission device is flexible rotation, no blockage, loose phenomenon.
Four. Test machine check
1, check the small gasoline engine is easy to start; 2, check the quality of the muffler; 3, check whether the vibration is too large after starting.
Through the above detailed introduction, I believe that you have a good understanding of the purchase of gasoline engine, better purchase.
