Remove the cover and remove the shaft from the cover by twisting it around while lifting up. Now remove the nut from the top of the shaft. Here comes the fun part... the shaft is really pressed hard onto the lever.
Proceed from here at your own risk. The end objective is to remove the lever, change it toward the motor by 2 splines (I think), and put it back together. If you have a press, it's easy.
You don't have a press so here is the backyard method. Put a spare nut on top of the shaft to protect the threads. support both sides of the lever with a vise and tap on the shaft to free it from the splines. Reset, then tab back through.
The end result is that you move the lever over the top of the motor so it's out of the way. You will have to cut the small return spring an inch or 2 and readjust your cable.
