Gasoline engine STX390 / L188F 13PS quality engine 389cm3


The petrol and diesel engines from all manufacturers are interchangeable regarding housing flange and crankshaft dimensions.
The crank shaft is standardized. The motor can therefore be used as a replacement engine that has the same crankshaft. A stock of spare parts with all wearing parts is available.
Thus, the owner of a bar mower, two wheel tractor, vibrating plate etc. can change his damaged or weak motor easily  - after the comparison of the crankshaft and flange dimension.

This petrol engine is First Hand and tested.
It is a replica of the Honda GX390 engine.
There are about 100 companies which produce replica engines in China. There are only a few with very good quality.

We have visited many engine manufacturers in China and have checked the production and quality control there. We noticed that the quality control was very well organized while we visited one of the largest manufacturers. All major components have been checked several times and during the production cycle many test stations were installed. During the visit of the production area and the outgoing goods warehouse we could see that the goods are made ​​for many well-known manufacturers / wholesale distributors in Europe and USA.

Therefore, we noted this company is very good.

I know broken connecting rods - wrong hardened / bent pulleys - plastic to soft / broken piston wall - cast aluminum to inferior etc.

This means that the engine is slightly more expensive - but it has a much better quality.

We guarantee a serious carrying out. You have a full right of return.
