you can't make frankenstein carbs and expect them to work. This is probably why you are getting no responses, it is somewhat inconceivable to me why you would try and mix up pieces. What exactly do you have that vacuum advance hooked up to anyway. Disconnect that and plug the "tube" that you have it hooked to. I have forgotten to re-connect the advance for quite some time (several months? before I noticed) and noticed no difference in the way it ran. You would probably do well to get the right carburetor, they aren't horribly expensive. I don't believe you will ever get that conglomeration to run.
