    I agree with the slide being worn from vibration, but how do you explain the other two pics that look like it has water damage? The vibration I have seen many times during carb overhauls, but the vibration damage doesn't leave that particular discolored residue in the bottom of the carb throat or in the bowl. That discoloration looks like where water has sat. The color can vary from white to greenish white. Plus water deposit on the slide can add to the slide damage from corroding the metal.

    As Roger stated, there may be some corrosion issues, especially if the carburetors don't have an airbox and the engine is exposed to the elements. It is difficult to tell without actually looking at the carburetors in person, however, corrosion is something you want to take into consideration.

    Any suggestions on where the water would come from?  The ship is kept with full covers over it in a hangar in central California when not regularly being flown.

    Doesn't look like water to me, just fretting corrosion.

    Just a thought - Condensation, particularly on metal surfaces, is a significant source of water in some climates/seasons
