Also, is the oil consumption the same on both carbs or is the consumption o=

Is the consumption of damper oil dependent on miles driven or on time betwe=
en refills (even if the car is not driven)?
My reasoning:=C2=A0 it is hard to imagine where that oil is going but if th=
e carb casting has porosity or some other leak maybe that is your problem.=
=C2=A0 Perhaps it would leak out regardless of amount of driving.=C2=A0-Rol=
