If no one comes up with the pdf file, you can always pull up the parts diagram for the handle and order the bushings. Pretty self explanatory as to how they are installed from the diagram...
Steering. Looks like the plastic bushings where the tiller arm attached to the motor are shot from years of tiller extension use. Unless when I get it apart the holes are worn out and I have to hone them and fit new bushings.What's sloppy the twist for the throttle or the steering back and fourth?
You might be right about the twist throttle being bad as well. When I pulled the handle off the bushing in the throttle was worn out and the slop had caused the plastic throttle handle to fit loose on the tiller arm. I couldn't tell if the spring needed to be replaced or not but I might as well, it's only a few dollars.What's sloppy the twist for the throttle or the steering back and fourth?
