Review: Exact fit for Wolf RX50 Scooter - I got this to replace a carb with a bad choke on a Wolf RX50 scooter. It shipped fast and had a good price. It was an exact fit and installed in about 1/2 hour. I didn't have to make any adjustments to the settings. It took a while to get started at first as it takes time to get the carb full of gasoline. Now the scooter starts instantly and runs great.

## Questions & Answers

**Q: does this carb work with my electric choke**

**Q: IS THIS A 19 MM CARBURATOR**
A: This carburetor has a 18.5 mm ID and a 28 mm OD

**Q: Is the mixture screw caped ?
Or do I have to adjust the mixture screw as well as the idle screw
