  • Is what it's supposed to be.
The delivery was actually 5 days early, and after opening the box, everything in the pictures above was included and looks really nice. After shopping around, this buyer was about 30-60 dollars cheaper than anyone else after shipping too.

  • Great motor
I am pleasantly surprised by the performance of this engine. It starts with one push of the accelerator and has not had any problems while driving. The price and quality are unbelievable!

  • Awesome product
I purchased this engine to replace the engine in a four-wheeler. The bolt type, exhaust pipe, and carburetor are all a perfect match. The power is also very good.
