I just purchased a new Super Z 60/28 EFI. The right control lever is lower (vertically) than the right and I see no way of making an adjustment to make both exactly level. Both levers are in upper holes. Levers are in alignment when in neutral position. Also when I push both levers fully forward the right lever goes farther than the left, and the mower pulls slighty to the right. I tried turning the stop screw clockwise that is in front of the right lever. By doing this it would not allow the right lever to go as far forward, but that only made it pull futher to the right. By decreasing the forward movement of right lever and and left staying the same, it will cause the mower to pull to the right. I read everything in the manual, but am still confused as how to address the situation. I know you would never be cutting with both levers fully forward, but I like to have things adjusted and in alignment. Anyone else deal with and solve this problem?
