Review: Best for the Price - I've been trying to fix up all my toys for spring, ended up needing a carb. I looked around and this is the best for the price. I have likes and dislikes, Its starts super easy, the choke doesn't vibrate itself out of place, it is a good increase in filter size, and it doesn't stall out at low speed as much. Its jetted a little low for me, my top speed is 15 mph lower and I'm now at 22mph. For installation its pretty simple there is no need for instructions, just use the adaptor and pipe tape (tape up the inlet tube and put adaptor over and its good to install). AND DON'T OVER TIGHTEN IT, most people who own these bikes don't have mechanical experience and they don't realize no matter what your engine and all parts for it are probably Chinese so you need to just get it snug. And keep your old carb you might need to switch the cable holder.
Review: Great item - Simple to install

### ⭐⭐⭐⭐ Good carb but read my review first.
*by K***N on July 18, 2025*

Carburetor isn't bad but dosen't come with any jets. I had to but a jet kit because the one jet in it is nowhere near the size for an 80cc. The jet size had to be reduced significantly to a #56, the stock jet was dumping an outrageous amount of fuel. This was purchased for a gas powered bicycle and after changing it the bike runs really good compared to the factory carb. When installing it do not crank on the screw, otherwise it will snap the carb mount. Be gentle with it plus it's not an off road machine so it will not fall off while riding down the street.
