An internal `cleaning' (de-varnishing) a method I recall (from *How to Keep
Your Volkswagen Alive*) is to slowly pour a quantity of diesel fuel down the
carburetor throat. Makes more sense than water, anyway.

Water injection reduces preignition tendencies. Thus, higher average
combustion chamber pressures can be achieved. Water injection is popular
with turbocharger folks.
