    Never mind the vacuum advance, first of all you need to get that puppy fired up!
    Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.

    Stick your hand on top the carb with no air cleaner when it's running, If it smooths out in some chance it could be vacume advance. It also may be running to lean

    Hey Dom;
    Your eratic idle is probably a mis-adjustment on the rockers, if you have just set them. If you need help, let me know!

    Your post doesn’t make sense. Are you saying that when you place it in gear with the advance hooked up, it dies?

    First of all, have you set the timing with a light to about 12 degrees advance with the vacuum disconnected?
    Secondly, try sucking on the vacuum advance hose with your mouth, does the idle bump up? Or, when you hook it to vacuum, does the idle bump up? If you can suck on the hose leading to the advance and if the vacuum does not stay on, your vacuum pod has a leak.
