Does anyone have the correct procedure to adjust the linkage on a Tri power set up? Tanx

I also have a 69-427 tri-power. The best way I've found is to make sure that there is a little play in the travel slot on the main carb when it's in the idel position. After all this linkage is designed to make sure the carbs close properly after letting up on the pedal. One more thing make sure your return spring is not hitting on the linkage behind the travel slot... some times it has the tendency to rub against it. GOOD-LUCK!
