RE: the ol' hose trick

[tr6taylor@webtv.net (Sally or Dick Taylor)]

John---We know a vacuum is there when a leak is present at the intake
manifold. Taking a bottle of propane, adding a flexible hose to the hard
nozzle allows one to bend the end around to different places, like under
the intake manifold. The engine will speed up when sucking in the
propane. I prefer this to carb cleaner and the like, esp. on hot
manifolds.
