I was just given a helix 150 that was parked many years ago. Fixed carb and now idles well. I originally could not get it to shift into gears but found how to do it. The issue now is that it shifts into reverse when in drive and drive when it isi reverse. Original owner says it was like that when he got it. My ADD will it allow me to operate this way. What is needed. I follow steps and diagrams well if anyone can tell me what to do to fix this. It works fine as is but drives me crazy knowing it is wrong.-thanks in advance-Clampett5
