All you really need in a third carb and some air cleaners.

Andy, you need to mention the throttle shafts will have to be modified, especially the middle carb needs a new, longer shaft. Too, the triple setup does not use that little "buffer" spring device between the stock dual carbs, just two stock "zig-zag" spring clips to lock the three shafts together. I had three like Strombergs rebuilt for my setup. The throttle shafts appoximate each other, almost touching where the spring clips hold them as one. The stock, modified (to Richard's specs) linkage is weak at best. That is why I too am awaiting Ab's cable linkage. The problem that I have encounted with using the modified stock linkage is the amount of natural (or because of wear) slop in the system which when I apply maximum pedal I still don't get maximum throttle opening. I can, from under the bonnet have someone sit in the car and in neutral, apply full throttle with the pedal and with by finger, push the throttle even further open and get quite a bit more rpms out of the engine. Thus, I am not able to get maximum acceleration, guessing I am leaving maybe 10% on the table.
