[Healeys] carb oil

[Richard Ewald]

::: Scratches head:::
The mixture would be too rich if the piston rises too slowly?
The higher the piston, the thinner the needle cross section at the top of
the jet.  The thinner the needle cross section the more fuel can be drawn
out of the jet.
So if too thick oil is used in the dash pots, the pistons will rise slower,
This would leave a thicker cross section of needle at the top of the jet,
and thus allow less fuel to be drawn into the engine.
Seems to me that using too thick an oil would give a lean mixture on a snap
throttle opening.
What am I missing?
