Tone arm slow on the drop

I recently purchased a used Basis 1400 with a Rega 250 arm. It had been in storage for some time. Works fine but when cueing up the play it is painfully slow to actually get down to the groove. This doesn't seem normal to me since I am comparing it to the last TT I used.
Is this function fluid dampened or adjustable? I want to give it a shot of WD 40 but, will hold off till I can hear from more patient people.
