RE: Throttle linkage?????
When I have tried the U bend, I have had more felx that I felt comfortable with. I use a bell crank. Usually I can mount some plywood to the engine mount and then install the bell crank on that. The ones made for CL have a bearing and work well, and are inexpensive. Serves the same puropose as the U bend, but with more positve control.
