[6pack] Carb dash pot oil

[Sally or Dick Taylor]

Steve---It would seem that the "best" dashpot oil depends on how rich or lean one has set the (adjustable type) carbs. Rich mixtures tolerate a thinner oil, which allows the air valves to rise a little quicker, without stumbling. Conversely, the lean-to-optimum air/fuel mix could require a thicker oil, such as the 20w/50.  It's easy enough to suck out the oil and try different blends, if you wish. Let the level of acceleration you desire determine the wt. of the oil. Tests need be taken well below the 3,000rpm mark, as the oil has very little influence on the rise of the pistons above this engine speed.
Best to leave the stock air valve springs in place, on street engines.
