One good way is to spray solvent (starting fluid, carb cleaner, etc.) at suspect areas. When the idle goes up, you've found your problem. You can also use propane by attaching a rubber hose extension to the torch head and flowing gas over suspect areas. Propane is less messy than solvents but more flammable, so you have to be careful.
