## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by J***E on June 15, 2025*

Put on weed eater and it started right up didn't even have to tune it . Was a really easy fix

### ⭐⭐⭐⭐⭐ Great product
*by C***S on June 23, 2025*

It works just right

### ⭐⭐⭐⭐ So far so good
*by D***S on July 31, 2021*

The carb arrived the next day as promised. I has read other reviews prior to purchasing this one. One review had said there was an idle speed issue after installing it. I noticed that the cable retainer end that attaches to the new carb was different than the original. If you use the new one, the throttle cable will be stretched out and will not allow the arm to go all the way back to low idle. This is a quick fix as long as you still have the original carb. Remove the small "C" clip from the original cable end and replace the one on the new carb. Works like a charm. I didn't use the enclosed green hose set, so I can't speak to that. As stated so far so good.
