Yeah 70 is the same, so hooked it up that way.

Funny, I've read all kinds of posts on setting the progressive linkage and adjusting so front carb comes in where you want it to.

from what I can see, there is no adjustment like that. If you try to make front carb come on sooner, you will lose FULL throttle/ WOT on both carbs.(ie. you will never get Both carbs WOT together)

Only way to set it AFAIK is to both carbs WOT like manual says.

Someone correct me if I'm missing something here : )
