Just buy a 6.5hp. Seriously, that kit is $129. You could buy a HF engine for less and if you have some cash to spare, buy some upgrades. Then you have a genuine Honda engine that you can pull parts from and install into your own engine. That would be the economical way to go but if you want to fix the gx, thats fine. My HF engine is mounted on my race kart and it goes about 45-50mph with absolutely no mods. Its amazing.
