There are several methods for locating vacuum leaks. Occasionally, you may experience a vacuum leak into the intake ports from the crankcase of the motor due to the intake manifold / cylinder head interface not being machined parallel. No amount of propane or carburetor cleaner will find such a leak. The best way is to insure the elimination of such a problem while building the motor. See the wiki article: [[Manifold/Head vacuum leak, internal]].

Hold bottle UPRIGHT during testing as liquid propane may run out of an inverted bottle.
