Screw a BS.
Get a honda clone for like 99 bucks.
They last just as long if you take care of them, and are easy to mod!
I have seen people turn a predator 212cc (6.5hp honda clone) into a 12hp for less then 200 bucks.
Plus if the engine does go out it's only 99 bucks for a new one.
Screw spending 200 plus on an engine that is BS.
