Soaking in carburetor cleaner of any kind simply softens the deposits. The true "cleaning" is done with high pressure compressed air- - - -LOTS of it! An instructor at the General Motors training center in Memphis where I spent a lot of time put it this way- - - -"Put 55 gallons of air through every hole you can find in that carburetor!" His point was this- - - -in order to function properly, the carb passages must be CLEAN and the only way to assure that happens is to use copious amounts of air to blow the crud out of them. Use a needle-point air gun and spend a ridiculous amount of time blowing the air through those passages, after softening the deposits with solvent AND doing a hot (almost boiling) water rinse of all the parts to neutralize the solvent. One of my auto mechanics students learned that last procedure the hard way. He didn't rinse- - - -just started to reassemble the carb while it was still wet with the dip cleaner. His hands started to tingle, so he went to the restroom to wash up. "Hmmmm- - - -gotta pee"- - - - - - -wrong move! Did you ever notice that the FIRST thing a mechanic does in a restroom is wash his hands? There's a very good reason for that!
