It works fine, but it doesn't fit MN D90 out of the box. The housing is slightly larger than the original and mounting holes doesn't match. I had to file quite an considerable amount of plastic in mounting holes, to be able to mount it... Shipping was extremely slow - more than two months - while lot of other packages ordered around the same time came between 20 and 30 days.
The engine works, but the power is not as great as i expected. My engine 180 is a same power.
This engine is weaker of my motor no 180. I am disappointed.
