## Questions & Answers

**Q: What non gravity fed carburetor would be compatible with this this motor the existing one is poorly designed?**
A: The TC Motor racing carburetor kit is what I used.  It's a great carb and performs wonderfly.  BUT, make sure you install a petcock, and MAKE SURE YOU CLOSE IT after you're done with the bike for the day, or it will flood, and you'll have a hard time starting it.

**Q: Is there a clutch on this engine**
A: Yes

**Q: Does rhis engine fit a scooter x goped?**
A: The original engine of scooter x is 62cc, and  the power is much bigger . It is supposed to change the engine mounting bracket when  installing our product.

**Q: Do you have to manually let off the clutch or does it do it on its own**
A: The clutch works automatically, and the combined speed is 4300 rpm.
