The dashpot is used to hold the throttle open on deceleration a short time- one to keep the engine from dieing from the rapid throttle closing, and two to help decrease emissions from the engine rapidly going rich due to the closed throttle.  With the engine off, crack open the throttle.  You will see the dashpot extend, then release the throttle and watch it slowly close as the dashpot retracts.

it also makes for a little bit smoother shifting, since the throttle doesn't slam closed as soon as you take your foot off the gas.
