Hello Michael,

I had always heard that you put the exact same oil in the damper as you put into the crankcase. That's WHY it takes a little less than 4 qts...   So you'll some left to top up the carbs!

The real answer is that the heavier the oil you put into the dashpot, the
longer it takes to respond to changes in the throttle position. While it is
opening, the mixture is richer due to the higher engine vacuum. This is
what compensates for the lack of a Holley-type accelerator pump. The
heavier your car and the less torque your engine has, the heavier the oil
you should run to cover flat spots in acceleration.

I took an experimental approach to this. I filled the dashpots with 15 
wt motorcycle fork oil, and half filled an oil can with the 15 wt. 
Acceleration was sluggish, so I added some 20 wt to the can, refilled 
the dashpots, and went for another test drive. If the engine seemed to 
be running rich on acceleration, I added 15 weight. if it seemed lean, I 
added 20 wt., changed out the oil, and went for another test drive. Not 
sure what the actual viscosity is, but it works well. Will have to 
recalibrate the oil after I change out the carb bushings and shafts.
