[TR] fuel mixture

[terryrs at comcast.net]

General Question:  I had the original metal air cleaners on the dual carbs for my '59 TR3A.  I did switch to paper filters.
Would the paper be a harder draw-through, maybe restricting air, making the car run richer than before?  In other words, does switching to paper necessarily mean I should lean the mixture by an 8th of a turn, something like that?
