Progressive linkage

[Anonymous]

Does anyone have plans, diagrams or a site where I can get some sort of info to enable me to make my own progressive linkage for a 3 bbl hookup? I am having trouble visualising how to get the two secondary carbs to be at WOT at the same time as the center carb! I have ran a couple of searches but can't even come up with pictures of one with enough detail to help.

Meanjean,

The center carb has a longer arm than the outside carbs to start out with, then the outside carbs are actuated by a sliding rod with adjustable stops on them.

If I can remember when I get home I think I have some pictures of my Offy set-up I'll post.

Of course you may be able to come up with a more intuitive set-up on your own.

See Ya,
Mike

Thanks Curtis, that shed a little light on my simple brain. I assume that around 2/3 throttle, the outer carbs start to open and are fully open at the same time as the center carb. Simple leverage must be designed into the linkage to accomplish this.
