"I'm working on a 4.3L v6
"I'm working on a 4.3L v6 mercruiser with the vacuum choke set up. Here's a picture.

My problem is in the choke linkage, I think. The butterfly on the carb stays open all the time. As you see it in the picture, when you start the engine the vacuum piston sucks in completely but the linkage arm just slides in the slot. I tried attaching the linkage arm to the single hole and this set up seemed much better. When the engine was not running the choke would completely close. While running the choke would open... but only 1/2 to 2/3 of the way open. There was not enough throw of the linkage arm to completely open the butterfly on the carb. How do you adjust this. Can I just straighten out the linkage arm to gain some more throw. There is a "V" shaped bend in the arm that is hard to see because its painted black - the same as the carb in the background. Thanks"
