    Nick!

    Tests for vacuum leaks that require the motor to be running often miss critical smaller fissures.

    An absolute test is performed while your carburetor is removed:
    http://virtualindian.org/11techleaktest.html.

    The manifold flange should be ground to flat, and the carburetor's flange lathe-dressed, as this interface cannot be bubble-tested.
    With carb installed, this seam, and the throttle bushings, may be inspected with an un-lit propane torch, although it will suffer the same lack of sensitivity as any other running test.

    No vacuum leak is an acceptible leak.

    I got my Rubber Ducky, hopefully will be able to work on the bike this week. A shout out to Cass at Deluxe Restorations in Dousman, WI, he had the "Ducky" in stock. He is following his passion and keeping our old iron alive
