hello again, things have been going well as far as repairs go but i have run into a problem, i found the ported vacuum switch under the intake manifold is missing a couple of the plastic nipples. i understand the emissions stuff is superfluous when running a weber carb, but i currently have the original mikuni carb which is working. i'm not having much luck finding a replacement and im curious as to what can be done and how important the valve is overall. from what i have read it shuts off the emissions stuff such as the EGR valve and the like while the engine is cold.
