## Customer Reviews

### ⭐⭐⭐⭐⭐ Fit my Tao Tao 50cc Perfectly
*by A***R on June 21, 2024*

Had a bad float needle in my old carburetor causing flooding. This is a direct replacement for the GY6 50cc that I have and worked better than the original. Only about 3 minutes of adjusting after install. Great inexpensive product. This version also has the threaded screws instead of the filled plugs that some have that allow for servicing and cleaning.

### ⭐⭐⭐⭐⭐ Just as described
*by I***A on December 7, 2024*

It's just as described. It was a gift

### ⭐⭐⭐⭐ It works better then stock.
*by J***T on December 17, 2024*

It fits well, quality is better than stock. Power and tuning are a lot easier, cleaning is too. Installing was cake .
