From your descriptions, all sound well.
One thing that is an unkonwn to me, as I never seen the inside of a model 16 machine, is where, and how the vacuum motor is positioned-situated within the machine, and by how and what means does the vacuum motor cause suction at the vacuum wand?
At least with the model 16.5, the priciple is basically simple, you have a vacuum motor butted up against one side of a baffled recovery tank, and in essence the vacuum wand at the other. There is a foam rubber seal on the 16.5 RCM, where the vacuum motor face butts up against the recovery tank. If this goes bad, which it can over time, proper sealing will be compromised, there will be a loss of vacuum pressure, and as well possible fluid leakage may occur at this area.
With my 16.5, basically all the fluids are off the record within one revolution. I do another revolution as insurance.
And as many others have found, more revolutions than 2 usually accomplish nothing more than than building a static charge due to a now dry wand rubbing the record's surface.
About the only other unknown I can think of mentioning, was what records did you note this with? Was this with just a few records that were used, that you've noticed this just lately, and only one occasion, or does this seem to be the norm, no matter what records you throw at your machine?
I ask this because records coming from some unknown source could possibly have been cleaned, and treated with something very stubborn to remove.
And that a repeat cleaning again had been the possible cause of positive results? Mark
