## Questions & Answers

**Q: 3 questions.... #1 Does this work with a #40 torque converter w/a 16 HP engine ?**
A: Yeah with the right pitch sprocket.

**Q: Why dose it go faster backwards? do i have it on wrong ? it goes pretty fast forward but takes of really slow but yet i can do a burnout backwards**
A: You have it being driven the wrong direction. Reverse is a lower gear then forward gear.

**Q: Does it have neutral?**
A: Yes

**Q: Will this work with a 20hp vertical shaft engine?**
A: Says up to 10hp. So your taking your chances. Be prepared for a lot of fabricating
