Q: Homebuilders throttle quadrants, Single handle Reversing vs. non reversing. What is the difference? I want to use with Bing carbs (Rotax 503).

A non-reversing quadrant will push or pull the cable attached in the same direction. If you push the lever forward the cable attached to it goes forward. A reversing quadrant is opposite. If you push the lever for forward, the cable attached to it goes the opposite direction, backward.
