Hi Dan!

We run just the tops of the pistons in the dashpots (the black plastic 
tops that screw on) and omit the oil.  What the oil does is damp the 
piston response so in your street car you have a smooth acceleration 
when you step on the pedal, and a smooth back-off when you take your 
foot off.  We want quick response in racing, not a slower damping of the 
effect -- I use my foot to modulate where I want the throttle to be and 
don't rely on damping. 

There has been a debate since the beginning of time (or at least since 
dashpot carbs were invented) about what oil to put in the pots.  I have 
always tried to use 3-in-1 oil in my street-car carbs, since it gives 
some damping effect but is still responsive the way I like it.  Others 
recommend just about any grade of engine oil, depending on who you talk to.


Keep Triumphing,
Susan      :)
