Not finding anything regarding this linkage we proceeded with the idea which we had designed earlier. Pictures illustrating the results of each step are attached.
The first step was to weld at about a 45 degree angle a 7" long, 1/2 inch square pipe to a 4" piece of 1 1/2" angle iron. Two holes were drilled into the angle iron for attachment to the engine through the use of two head bolts. The front end of the head appeared to be the best location for alignment with the pertinent points of attachment.
Bob then welded a 4" long 1/2" piece of pipe with an inside i.d. of 1/4" to the top of the square pipe to form a "T".
He inserted a smaller i.d. bolt through the pipe and then welded a 3" piece of 1" flat strap to each end of the bolt to form a pair of "arms" that would turn freely on the "T" pipe.
A swivel post was bolted to the end of each piece of flat strap and the rods to the pedal ball and carbuerator were attached to their respective "arms".
Bob did such a great job with the welding that the only thing else he needed to do was to bend the "spoon" on the gas pedal down so that the sole of his foot touched the flat of the "spoon" instead of the edge!
All functioned great!

Jim
