Classics,
I recently swapped my 216 for a newer 235. I was able to utilize the same linkage from the carb to the swivel point on the block. I did have to shorten the rod from the pedal to the swivel point. Just measure, measure a second time and cut the rod. Don’t forget to leave a 3/8 extra. You’ll need to heat and bend that 3/8 to a 90 degree bend for the swivel connection. Then drill a hole for the cotter pin.
