<VV> Leak Detecting...

A little bottle of propane is less messy than WD 40  FWIW.

  "...An engine tuner once told us that 90 percent of all drivability 
  problems could be traced to vacuum leaks. If your street motor 
  is suffering from part-throttle hiccups or the lean-surge blues, 
  take a few minutes to search for a vacuum leak, first make 
  sure all the carb and intake-manifold bolts are tight. 

  Also make sure all the vacuum outlets on the engine are closed off 
  and that all vacuum lines are intact. It's common to discover a rubber 
  vacuum plug is missing or cracked. If everything is secure, start 
  the engine, warm it up, and shoot short squirts of WD-40 around 
  the intake and the carb and listen for a change in idle speed. 

  If you locate an area where the engine speed increases when you hit it 
  with WD-40, then you've found a vacuum leak. The engine speed
  increases because the leak pulls the WD-40 into the engine and 
  burns it, temporarily increasing engine speed. This can make a 
  mess that will have to be cleaned, but it works to locate 
  hard-to-find vacuum leaks..."
