[Healeys] carb oil

[David Nock]

The viscosity of the oil is not that critical as long as you don't  
use a 90 wt oil. We have used standard engine oil in the dash pots  
for years.

The oil is there mostly to damper the piston during cruising speeds  
and also stop the piston form going up to fast upon acceleration.

If you use a oil that you use is way to thick the piston will be slow  
to rise and you will have a little to rich mixture when accelerating.
