im wondering how much hoses you can cap off on the hitachi carb before it dosn't work....this is on my 84 wagen. my dad has already caped off a few hoses here and there and it has continued to pass emissions even without a cat. im just wondering what i should not cap off..I know very little about this carb and it seems it has some crazy vacume choke or some sort of vacume deal that opens the second butterfly...

?

well, you could always just try a bunch of stuff out and see what works and what does not. with the engine running, try capping things off one at a time and listen for a change in the idle. if it goes crazy on you, it might be a good idea to leave that one open.
