If you do not SEE the slowess... the dashpot should be replaced (they are getting SCARCE).

You will need to have the THROTTLE RETURN DASH-POT on your (unspecified) carburetor tested and adjusted... and the IDLE SPEED correctly set.
Idle Speed and a slow rate of RPM reduction is critical to the proper function...
Some LESSOR "mechanics" will attempt to raise the IDLE SPEED to compensate for a malfunctioning DASHPOT... This will PROFOUNDLY exacerbate the problem.
