Airspeed issue

[Dana]

I think something's wonky with my airspeed indicator. There seems to be a lot of lag. My Starduster stalls at 50 indicated when I slow it up gradually, but I can lift off at an indicated 45, then it seems to take a long time to accelerate (at least according to the ASI). But doing a full stall (tailwheel touching first) landing, it's indicating 60 at the moment of touchdown. Perhaps a partial blockage in the pitot line somewhere?
