This honda engine is quiet, starts quick and with ease. It also uses very little fuel. When a person does his regular maintenance a Honda will last forever!

Great Quality Engine
By Burke F.

Review Posted 03/29/2017 
It started right up after oil and gas were put in. There was some question as to whether it would bolt up to my power screen with no adaptations. I am happy to report that it did. This was replacing a GX 22.

Nice small motor

Review Posted 10/31/2016 
Used this motor to build a small go kart for my grandson and it is working out great so far. Only thing I'm not crazy about is all my other Honda's start first pull and this one tales about 5 to 6 pulls but runs great.
